-Copying all data types to the clipboard
-==============================================
-
-There already exists an escape code to allow terminal programs to
-read/write plain text data from the system clipboard, *OSC 52*.
-kitty introduces a more advanced protocol that supports:
-
-* Copy arbitrary data including images, rich text documents, etc.
-* Allow terminals to ask the user for permission to access the clipboard and
-  report permission denied
-
-The escape code is *OSC 5522*, an extension of *OSC 52*. The basic format
-of the escape code is::
-
-    <OSC>5522;metadata;payload<ST>
-
-Here, *metadata* is a colon separated list of key-value pairs and payload is
-base64 encoded data. :code:`OSC` is :code:`<ESC>[`.
-:code:`ST` is the string terminator, :code:`<ESC>\\`.
-
-Reading data from the system clipboard
-----------------------------------------
-
-To read data from the system clipboard, the escape code is::
-
-    <OSC>5522;type=read;<base 64 encoded space separated list of mime types to read><ST>
-
-For example, to read plain text and PNG data, the payload would be::
-
-    text/plain image/png
-
-encoded as base64. To read from the primary selection instead of the
-clipboard, add the key ``loc=primary`` to the metadata section.
-
-To get the list of MIME types available on the clipboard the payload must be
-just a period (``.``), encoded as base64.
-
-The terminal emulator will reply with a sequence of escape codes of the form::
-
-    <OSC>5522;type=read:status=OK<ST>
-    <OSC>5522;type=read:status=DATA:mime=<base 64 encoded mime type>;<base64 encoded data><ST>
-    <OSC>5522;type=read:status=DATA:mime=<base 64 encoded mime type>;<base64 encoded data><ST>
-    .
-    .
-    .
-    <OSC>5522;type=read:status=DONE<ST>
-
-Here, the ``status=DATA`` packets deliver the data (as base64 encoded bytes)
-associated with each MIME type. The terminal emulator should chunk up the data
-for an individual type. A recommended size for each chunk is 4096 bytes. All
-the chunks for a given type must be transmitted sequentially and only once they
-are done the chunks for the next type, if any, should be sent. The end of data
-is indicated by a ``status=DONE`` packet.
-
-If an error occurs, instead of the opening ``status=OK`` packet the terminal
-must send a ``status=ERRORCODE`` packet. The error code must be one of:
-
-``status=ENOSYS``
-    Sent if the requested clipboard type is not available. For example, primary
-    selection is not available on all systems and ``loc=primary`` was used.
-
-``status=EPERM``
-    Sent if permission to read from the clipboard was denied by the system or
-    the user.
-
-``status=EBUSY``
-    Sent if there is some temporary problem, such as multiple clients in a
-    multiplexer trying to access the clipboard simultaneously.
-
-Terminals should ask the user for permission before allowing a read request.
-However, if a read request only wishes to list the available data types on the
-clipboard, it should be allowed without a permission prompt. This is so that
-the user is not presented with a double permission prompt for reading the
-available MIME types and then reading the actual data.
-
-
-Writing data to the system clipboard
-----------------------------------------
-
-To write data to the system clipboard, the terminal programs sends the
-following sequence of packets::
-
-    <OSC>5522;type=write<ST>
-    <OSC>5522;type=wdata:mime=<base64 encoded mime type>;<base 64 encoded chunk of data for this type><ST>
-    <OSC>5522;type=wdata:mime=<base64 encoded mime type>;<base 64 encoded chunk of data for this type><ST>
-    .
-    .
-    .
-    <OSC>5522;type=wdata<ST>
-
-The final packet with no mime and no data indicates end of transmission. The
-data for every MIME type should be split into chunks of no more than 4096
-bytes. All the chunks for a given MIME type must be sent sequentially, before
-sending chunks for the next MIME type. After the transmission is complete, the
-terminal replies with a single packet indicating success::
-
-    <OSC>5522;type=write:status=DONE<ST>
-
-If an error occurs the terminal can, at any time, send an error packet of the
-form::
-
-    <OSC>5522;type=write:status=ERRORCODE<ST>
-
-Here ``ERRORCODE`` must be one of:
-
-``status=EIO``
-    An I/O error occurred while processing the data
-``status=EINVAL``
-    One of the packets was invalid, usually because of invalid base64 encoding.
-``status=ENOSYS``
-    The client asked to write to the primary selection with (``loc=primary``) and that is not
-    available on the system
-``status=EPERM``
-    Sent if permission to write to the clipboard was denied by the system or
-    the user.
-``status=EBUSY``
-    Sent if there is some temporary problem, such as multiple clients in a
-    multiplexer trying to access the clipboard simultaneously.
-
-Once an error occurs, the terminal must ignore all further OSC 5522 write related packets until it
-sees the start of a new write with a ``type=write`` packet.
-
-The client can send to the primary selection instead of the clipboard by adding
-``loc=primary`` to the initial ``type=write`` packet.
-
-Finally, clients have the ability to *alias* MIME types when sending data to
-the clipboard. To do that, the client must send a ``type=walias`` packet of the
-form::
-
-    <OSC>5522;type=walias;mime=<base64 encoded target MIME type>;<base64 encoded, space separated list of aliases><ST>
-
-The effect of an alias is that the system clipboard will make available all the
-aliased MIME types, with the same data as was transmitted for the target MIME
-type. This saves bandwidth, allowing the client to only transmit one copy of
-the data, but create multiple references to it in the system clipboard. Alias
-packets can be sent anytime after the initial write packet and before the end
-of data packet.
-
-
-Support for terminal multiplexers
-------------------------------------
-
-Since this protocol involves two way communication between the terminal
-emulator and the client program, multiplexers need a way to know which window
-to send responses from the terminal to. In order to make this possible, the
-metadata portion of this escape code includes an optional ``id`` field. If
-present the terminal emulator must send it back unchanged with every response.
-Valid ids must include only characters from the set: ``[a-zA-Z0-9-_+.]``. Any
-other characters must be stripped out from the id by the terminal emulator
-before retransmitting it.
-
-Note that when using a terminal multiplexer it is possible for two different
-programs to tread on each others clipboard requests. This is fundamentally
-unavoidable since the system clipboard is a single global shared resource.
-However, there is an additional complication where responses form this protocol
-could get lost if, for instance, multiple write requests are received
-simultaneously. It is up to well designed multiplexers to ensure that only a
-single request is in flight at a time. The multiplexer can abort requests by
-sending back the ``EBUSY`` error code indicating some other window is trying
-to access the clipboard.

 Using a color theme with a background color does not work well in vim?

-Sadly, vim has very poor out-of-the-box detection for modern terminal features.

+I get errors about the terminal being unknown or opening the terminal failing when SSHing into a different computer?
+-----------------------------------------------------------------------------------------------------------------------
+
+This happens because the |kitty| terminfo files are not available on the server.
+You can ssh in using the following command which will automatically copy the
+terminfo files to the server::
 
     kitty +kitten ssh myserver
 
-It will automatically copy over the terminfo files and also magically enable
-:doc:`shell integration </shell-integration>` on the remote machine.
-
 This :doc:`ssh kitten <kittens/ssh>` takes all the same command line arguments
 as :program:`ssh`, you can alias it to something small in your shell's rc files
 to avoid having to type it each time::
 
     alias s="kitty +kitten ssh"
 
-If this does not work, see :ref:`manual_terminfo_copy` for alternative ways to
-get the kitty terminfo files onto a remote computer.
+If the ssh kitten fails, use the following one-liner instead (it is slower as it
+needs to ssh into the server twice, but will work with most servers)::
 
-The next most common reason for this is if you are running commands as root
-using :program:`sudo` or :program:`su`. These programs often filter the
-:envvar:`TERMINFO` environment variable which is what points to the kitty
-terminfo files.
+    infocmp -a xterm-kitty | ssh myserver tic -x -o \~/.terminfo /dev/stdin
 
-First, make sure the :envvar:`TERM` is set to ``xterm-kitty`` in the sudo
-environment. By default, it should be automatically copied over.
+If you are behind a proxy (like Balabit) that prevents this, or :program:`tic`
+comes with macOS that does not support reading from STDIN, you must redirect the
+first command to a file, copy that to the server and run :program:`tic`
+manually. If you connect to a server, embedded or Android system that doesn't
+have :program:`tic`, copy over your local file terminfo to the other system as
+:file:`~/.terminfo/x/xterm-kitty`.
 
-If you are using a well maintained Linux distribution, it will have a
-``kitty-terminfo`` package that you can simply install to make the kitty
-terminfo files available system-wide. Then the problem will no longer occur.
+Really, the correct solution for this is to convince the OpenSSH maintainers to
+have :program:`ssh` do this automatically, if possible, when connecting to a
+server, so that all terminals work transparently.
 
-Alternately, you can configure :program:`sudo` to preserve :envvar:`TERMINFO`
-by running ``sudo visudo`` and adding the following line::
+If the server is running FreeBSD, or another system that relies on termcap
+rather than terminfo, you will need to convert the terminfo file on your local
+machine by running (on local machine with |kitty|)::
+
+    infocmp -CrT0 xterm-kitty
+
+The output of this command is the termcap description, which should be appended
+to :file:`/usr/share/misc/termcap` on the remote server. Then run the following
+command to apply your change (on the server)::
+
+    cap_mkdb /usr/share/misc/termcap
+
+
+Keys such as arrow keys, backspace, delete, home/end, etc. do not work when using su or sudo?
+-------------------------------------------------------------------------------------------------
+
+Make sure the :envvar:`TERM` environment variable, is ``xterm-kitty``.  And
+either the :envvar:`TERMINFO` environment variable points to a directory
+containing :file:`x/xterm-kitty` or that file is under :file:`~/.terminfo/x/`.
+
+For macOS, you may also need to put that file under :file:`~/.terminfo/78/`::
+
+    mkdir -p ~/.terminfo/{78,x}
+    ln -snf ../x/xterm-kitty ~/.terminfo/78/xterm-kitty
+    tic -x -o ~/.terminfo "$KITTY_INSTALLATION_DIR/terminfo/kitty.terminfo"
+
+Note that :program:`sudo` might remove :envvar:`TERMINFO`. Then setting it at
+the shell prompt can be too late, because command line editing may not be
+reinitialized. In that case you can either ask :program:`sudo` to set it or if
+that is not supported, insert an :program:`env` command before starting the
+shell, or, if not possible, after sudo start another shell providing the right
+terminfo path::
+
+    sudo … TERMINFO=$HOME/.terminfo bash -i
+    sudo … env TERMINFO=$HOME/.terminfo bash -i
+    TERMINFO=/home/ORIGINALUSER/.terminfo exec bash -i
+
+You can configure :program:`sudo` to preserve :envvar:`TERMINFO` by running
+``sudo visudo`` and adding the following line::
 
     Defaults env_keep += "TERM TERMINFO"
 
-If none of these are suitable for you, you can run sudo as follows::
-
-    sudo TERMINFO="$TERMINFO" -s -H
-
-This will start a new root shell with the correct :envvar:`TERMINFO` value from your
-current environment copied over.
-

 explicitly set a UTF-8 locale, like::

-
-Unicode placeholders
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. versionadded:: 0.28.0
-   Support for image display via Unicode placeholders
-
-You can also use a special Unicode character ``U+10EEEE`` as a placeholder for
-an image. This approach is less flexible, but it allows using images inside
-any host application that supports Unicode and foreground colors (tmux, vim, weechat, etc.)
-and has a way to pass escape codes through to the underlying terminal.
-
-The central idea is that we use a single *Private Use* Unicode character as a
-*placeholder* to indicate to the terminal that an image is supposed to be
-displayed at that cell. Since this character is just normal text, Unicode aware
-application will move it around as needed when they redraw their screens,
-thereby automatically moving the displayed image as well, even though they know
-nothing about the graphics protocol. So an image is first created using the
-normal graphics protocol escape codes (albeit in quiet mode (``q=2``) so that there are
-no responses from the terminal that could confuse the host application). Then,
-the actual image is displayed by getting the host application to emit normal
-text consisting of ``U+10EEEE`` and various diacritics (Unicode combining
-characters) and colors.
-
-To use it, first create an image as you would normally with the graphics
-protocol with (``q=2``), but do not create a placement for it, that is, do not
-display it. Then, create a *virtual image placement* by specifying ``U=1`` and
-the desired number of lines and columns::
-
-    <ESC>_Ga=p,U=1,i=<image_id>,c=<columns>,r=<rows><ESC>\
-
-The creation of the placement need not be a separate escape code, it can be
-combined with ``a=T`` to both transmit and create the virtual placement with a
-single code.
-
-The image will eventually be fit to the specified rectangle, its aspect ratio
-preserved. Finally, the image can be actually displayed by using the
-placeholder character, encoding the image ID in its foreground color. The row
-and column values are specified with diacritics listed in
-:download:`rowcolumn-diacritics.txt <../rowcolumn-diacritics.txt>`.  For
-example, here is how you can print a ``2x2`` placeholder for image ID ``42``:
-
-.. code-block:: sh
-
-    printf "\e[38;5;42m\U10EEEE\U0305\U0305\U10EEEE\U0305\U030D\e[39m\n"
-    printf "\e[38;5;42m\U10EEEE\U030D\U0305\U10EEEE\U030D\U030D\e[39m\n"
-
-Here, ``U+305`` is the diacritic corresponding to the number ``0``
-and ``U+30D`` corresponds to ``1``. So these two commands create the following
-``2x2`` placeholder:
-
-========== ==========
-(0, 0)     (1, 0)
-(1, 0)     (1, 1)
-========== ==========
-
-This will cause the image with ID ``42`` to be displayed in a ``2x2`` grid.
-Ideally, you would print out as many cells as the number of rows and columns
-specified when creating the virtual placement, but in case of a mismatch only
-part of the image will be displayed.
-
-By using only the foreground color for image ID you are limited to either 8-bit IDs in 256 color
-mode or 24-bit IDs in true color mode. Since IDs are in a global namespace
-there can easily be collisions. If you need more bits for the image
-ID, you can specify the most significant byte via a third diacritic. For
-example, this is the placeholder for the image ID ``33554474 = 42 + (2 << 24)``:
-
-.. code-block:: sh
-
-    printf "\e[38;5;42m\U10EEEE\U0305\U0305\U030E\U10EEEE\U0305\U030D\U030E\n"
-    printf "\e[38;5;42m\U10EEEE\U030D\U0305\U030E\U10EEEE\U030D\U030D\U030E\n"
-
-Here, ``U+30E`` is the diacritic corresponding to the number ``2``.
-
-You can also specify a placement ID using the underline color (if it's omitted
-or zero, the terminal may choose any virtual placement of the given image). The
-background color is interpreted as the background color, visible if the image is
-transparent. Other text attributes are reserved for future use.
-
-Row, column and most significant byte diacritics may also be omitted, in which
-case the placeholder cell will inherit the missing values from the placeholder
-cell to the left, following the algorithm:
-
-- If no diacritics are present, and the previous placeholder cell has the same
-  foreground and underline colors, then the row of the current cell will be the
-  row of the cell to the left, the column will be the column of the cell to the
-  left plus one, and the most significant image ID byte will be the most
-  significant image ID byte of the cell to the left.
-- If only the row diacritic is present, and the previous placeholder cell has
-  the same row and the same foreground and underline colors, then the column of
-  the current cell will be the column of the cell to the left plus one, and the
-  most significant image ID byte will be the most significant image ID byte of
-  the cell to the left.
-- If only the row and column diacritics are present, and the previous
-  placeholder cell has the same row, the same foreground and underline colors,
-  and its column is one less than the current column, then the most significant
-  image ID byte of the current cell will be the most significant image ID byte
-  of the cell to the left.
-
-These rules are applied left-to-right, which allows specifying only row
-diacritics of the first column, i.e. here is a 2 rows by 3 columns placeholder:
-
-.. code-block:: sh
-
-    printf "\e[38;5;42m\U10EEEE\U0305\U10EEEE\U10EEEE\n"
-    printf "\e[38;5;42m\U10EEEE\U030D\U10EEEE\U10EEEE\n"
-
-This will not work for horizontal scrolling and overlapping images since the two
-given rules will fail to guess the missing information. In such cases, the
-terminal may apply other heuristics (but it doesn't have to).
-
-It is important to distinguish between virtual image placements and real images
-displayed on top of Unicode placeholders. Virtual placements are invisible and only play
-the role of prototypes for real images. Virtual placements can be deleted by a
-deletion command only when the `d` key is equal to ``i``, ``I``, ``n`` or ``N``.
-The key values ``a``, ``c``, ``p``, ``q``, ``x``, ``y``, ``z`` and their capital
-variants never affect virtual placements because they do not have a physical
-location on the screen.
-
-Real images displayed on top of Unicode placeholders are not considered
-placements from the protocol perspective. They cannot be manipulated using
-graphics commands, instead they should be moved, deleted, or modified by
-manipulating the underlying Unicode placeholder as normal text.

-If the server is running a relatively modern Linux distribution and you have

-Async and streaming requests
----------------------------------
-
-Some remote control commands require asynchronous communication, that is, the
-response from the terminal can happen after an arbitrary amount of time. For
-example, the :code:`select-window` command requires the user to select a window
-before a response can be sent. Such command must set the field :code:`async`
-in the JSON block above to a random string that serves as a unique id. The
-client can cancel an async request in flight by adding the :code:`cancel_async`
-field to the JSON block. A async response remains in flight until the terminal
-sends a response to the request. Note that cancellation requests dont need to
-be encrypted as users must not be prompted for these and the worst a malicious
-cancellation request can do is prevent another sync request from getting a
-response.
-
-Similar to async requests are *streaming* requests. In these the client has to
-send a large amount of data to the terminal and so the request is split into
-chunks. In every chunk the JSON block must contain the field ``stream`` set to
-``true`` and ``stream_id`` set to a random long string, that should be the same for
-all chunks in a request. End of data is indicated by sending a chunk with no data.

-is used, as a fallback. Can be specified multiple times to create multiple
-aliases. For example: :code:`--alias text/plain=text/x-rst` makes :code:`text/plain` an alias
-of :code:`text/rst`. Aliases are not used in filter mode. An alias for
