+
+- Add a :opt:`resize_in_steps` option that can be used to resize the OS window

+
+- When triple-click+dragging to select multiple lines, extend the selection
+  of the first line to match the rest on the left (:pull:`2284`)
+

+  :opt:`hide_window_decorations` to only hide the title bar (:pull:`2286`)
+
+- Fix a segfault when using :option:`kitty --debug-config` with maps (:iss:`2270`)
+
+- ``goto_tab`` now maps numbers larger than the last tab to the last tab
+  (:iss:`2291`)
+
+- Fix URL detection not working for urls of the form scheme:///url
+  (:iss:`2292`)
+
+- When windows are semi-transparent and all contain graphics, correctly render
+  them. (:iss:`2310`)
+
+0.15.1 [2019-12-21]
+--------------------
+
+- Fix a crash/incorrect rendering when detaching a window in some circumstances

+
+- Add a new action :ref:`detach_window <detach_window>` that can be used to move the current
+  window into a different tab (:iss:`1310`)
+
+- Add a new action :doc:`launch <launch>` that unifies launching of processes
+  in new kitty windows/tabs.

+  (:iss:`1869`)

+  such as Nimbus Mono.
+
+- Fix a regression that broke setting background_opacity via remote control
+  (:iss:`1895`)
+
+- Fix piping PNG images into the icat kitten not working (:iss:`1920`)

+This is accomplished by using ``map`` with :sc:`send_text <send_text>` in :file:`kitty.conf`.
+For example::

+
+This maps :kbd:`alt+s` to :kbd:`ctrl+s`. To figure out what bytes to use for

+

+       page <http://ascii-table.com/ansi-escape-sequences.php>`_ or any
+       ANSI escape sequence table. There are different modifiers for :kbd:`ctrl`,

+--------------------------
+
+When using :option:`launch --stdin-source`, the program to which the data is
+piped has a special environment variable declared, ``KITTY_PIPE_DATA`` whose
+contents are::
+
+   KITTY_PIPE_DATA={scrolled_by}:{cursor_x},{cursor_y}:{lines},{columns}
+
+where ``scrolled_by`` is the number of lines kitty is currently scrolled by,
+``cursor_(x|y)`` is the position of the cursor on the screen with ``(1,1)``
+being the top left corner and ``{lines},{columns}`` being the number of rows
+and columns of the screen.

+Marks
+=================
+
+
+kitty has the ability to mark text on the screen based on regular expressions.
+This can be useful to highlight words or phrases when browsing output from long
+running programs or similar. Lets start with a few examples:
+
+Suppose we want to be able to highlight the word ERROR in the current window.
+Add the following to :file:`kitty.conf`::
+
+    map f1 toggle_marker text 1 ERROR
+
+Now when you press :kbd:`F1` all instances of the word :code:`ERROR` will be
+highlighted. To turn off the highlighting, press :kbd:`F1` again.
+If you want to make it case-insensitive, use::
+
+    map f1 toggle_marker itext 1 ERROR
+
+To make it match only complete words, use::
+
+    map f1 toggle_marker regex 1 \bERROR\b
+
+Suppose you want to highlight both :code:`ERROR` and :code:`WARNING`, case
+insensitively::
+
+    map f1 toggle_marker iregex 1 \bERROR\b 2 \bWARNING\b
+
+kitty supports up to 3 mark groups (the numbers in the commands above). You
+can control the colors used for these groups in :file:`kitty.conf` with::
+
+    mark1_foreground red
+    mark1_background gray
+    mark2_foreground green
+    ...
+
+
+.. note::
+    For performance reasons, matching is done per line only, and only when that line is
+    altered in any way. So you cannot match text that stretches across multiple
+    lines.
+
+
+Creating markers dynamically
+---------------------------------
+
+If you want to create markers dynamically rather than pre-defining them in
+:file:`kitty.conf` you can do so as follows::
+
+    map f1 create_marker
+    map f2 remove_marker
+
+Then pressing :kbd:`F1` will allow you to enter the marker definition and set
+it and pressing :kbd:`F2` will remove the marker.
+
+You can also use the facilities for :doc:`remote-control` to dynamically
+add/remove markers.
+
+
+Scrolling to marks
+--------------------
+
+kitty has an action to scroll to the next line that contains a mark. You can
+use it by mapping it to some shortcut in :file:`kitty.conf`::
+
+    map ctrl+p scroll_to_mark prev
+    map ctrl+n scroll_to_mark next
+
+Then pressing :kbd:`ctrl+p` will scroll to the first line in the scrollback
+buffer above the current top line that contains a mark. Pressing :kbd:`ctrl+n`
+will scroll to show the first line below the current last line that contains
+a mark. If you wish to jump to a mark of a specific type, you can add that to
+the mapping::
+
+    map ctrl+1 scroll_to_mark prev 1
+
+Which will scroll only to marks of type 1.
+
+
+The full syntax for creating marks
+-------------------------------------
+
+The syntax of the :code:`toggle_marker` command is::
+
+    toggle_marker <marker-type> <specification>
+
+Here :code:`marker-type` is one of:
+
+    * :code:`text` - simple substring matching
+    * :code:`itext` - case-insensitive substring matching
+    * :code:`regex` - A python regular expression
+    * :code:`iregex` - A case-insensitive python regular expression
+    * :code:`function` - An arbitrary function defined in a python file, see
+      :ref:`marker_funcs`.
+
+.. _marker_funcs:
+
+Arbitrary marker functions
+-----------------------------
+
+You can create your own marker functions. Create a python file named
+:file:`mymarker.py` and in it create a :code:`marker` function. This
+function receives the text of the line as input and must yield three numbers,
+the starting character position, the ending character position and the mark
+group (1-3). For example:
+
+.. code-block::
+
+    def marker(text):
+        # Function to highlight the letter X
+        for i, ch in enumerate(text):
+            if ch.lower() == 'x':
+                yield i, i, 3
+
+
+Save this file somewhere and in :file:`kitty.conf`, use::
+
+    map f1 toggle_marker function /path/to/mymarker.py
+
+If you save the file in the kitty config directory, you can use::
+
+    map f1 toggle_marker function mymarker.py

+Documentation for the kitty remote control protocol
+======================================================
+
+The kitty remote control protocol is a simple protocol that involves sending
+data to kitty in the form of JSON. Any individual command of kitty has the
+form::
+
+    <ESC>P@kitty-cmd<JSON object><ESC>\
+
+Where ``<ESC>`` is the byte ``0x1b``. The JSON object has the form::
+
+    {
+        'cmd': "command name",
+        'version': "kitty version",
+        'no_response': Optional Boolean,
+        'payload': <Optional JSON object>,
+    }
+
+The ``version`` above is a string of the form :code:`0.14.2`. If you are developing a
+standalone client, use the kitty version that you are developing against. Using
+a version greater than the version of the kitty instance you are talking to,
+will cause a failure.
+
+Set ``no_response`` to True if you don't want a response from kitty.
+
+The optional payload is a JSON object that is specific to the actual command being sent.
+The fields in the object for every command are documented below.
