Fix function key definitions in terminfo/termcap

[shimt]

Fix modifier key + F3 does not work in current terminfo/termcap.

Before (0.27.0):

Key	Kitty Output	Terminfo Variable	Terminfo Value
F3	SS3 OR	kf3	SS3 OR
Shift F3	CSI 13;2~	kf15	CSI 1;2R
Ctrl F3	CSI 13;5~	kf27	CSI 1;5R
Alt F3	CSI 13;3~	kf51	CSI 1;3R
Shift + Alt F3	CSI 13;4~	kf63	CSI 1;4R

After:

Key	Kitty Output	Terminfo Variable	Terminfo Value
F3	SS3 OR	kf3	SS3 OR
Shift F3	CSI 13;2~	kf15	CSI 13;2~
Ctrl F3	CSI 13;5~	kf27	CSI 13;5~
Alt F3	CSI 13;3~	kf51	CSI 13;3~
Shift + Alt F3	CSI 13;4~	kf63	CSI 13;4~

I'm not sure where I should be asking this, but since v0.27.0 I've noticed that Ctrl F3 seems to not work in tmux, it just prints out 3;5~, while Ctrl F1, Ctrl F2 and Ctrl F4 do work.

I'm using v0.26.5 in the meantime.

What more info can I provide?

There isnt anything to provide, assuming you are running kitty 0.27.1 in
which this bug was fixed, it should work in tmux out of the box, it does
for me.

Huh, that's odd, it does work.

I must've had v0.27.0 still running after updating. Sorry for the noise!

[mark2185]

Sorta kinda related, but now after updating to latest kitty I've discovered something yet again related to tmux.

Opening up FZF in vim (which brings up a popup terminal where the user can input text) allows the user to press ctrl+/ to hide the preview of searched files, and that works, but only in tmux.
When the combination ctrl+/ is pressed outside of tmux, it inserts ;5u.

So, in short, running vim +FZF and pressing ctrl+/ inputs ;5u, but running tmux && vim +FZF and pressing ctrl+/ works as expected.

kitty --version gives 0.28.1. What else can I provide?

This will be a bug in vim, tmux filters out the kitty keyboard protocol
events. Update vim, or if it is already updated report the issue there.
And dont forget to follow the instructions in the kitty FAQ about vim.
