If you are trying to integrate icat into another program like a file
manager, there are a couple of things to keep in mind. icat works by
communicating over the TTY device, it both writes to and reads from the TTY.
So it is imperative that while it is running the host program does not do
any TTY I/O. And any key presses or other input from the user on the TTY
device will be discarded. At a minimum, you should use the
:option:`kitty +kitten icat --silent` and :option:`kitty +kitten icat --transfer-mode` flags. To be really robust
you should consider writing proper support for the
:doc:`../graphics-protocol` in the program instead.
Nowadays there are many libraries that have support for it.
