kitty writes strange characters when pressing keyboard shortcuts

[flexusjan]

Describe the bug Pressing some shortcuts writes strange characters in the Kitty Terminal.

For example: shift+f1 prints "P" shift+f2 prints "Q" ctrl+f5 prints ";2~" shift+left prints "D" ... and many more

Pressing the same shortcuts in other Terminal-Emulators or Text-Editors doesn't print any characters.

To Reproduce Steps to reproduce the behavior:

1. start kitty
2. press shift+f1

Expected behavior Most of the shortcuts shouldn't print anything

Additional context Try to reproduce the problem with kitty --config NONE if you cannot then post a minimal kitty.conf that reproduces the problem. If the problem involves interaction with some other terminal program post a minimal config for that program to reproduce the problem as well.

Same behavior with kitty --config NONE.

Its a feature see #3248

[Cypher1]

Is there a way to turn this 'feature' off? Personally, I don't want P and similar characters when I try to open my Whisker (Start) Menu.

@Cypher1

If you often press other software shortcuts (or similar shortcuts) in kitty by mistake, you can configure the key action as discard_event and kitty will completely ignore the key and will not send the corresponding escape sequence to the program in the window.

map shift+f1 discard_event
