kitty shortcut ctrl+shift issue

[christos-stamatis]

Hi everyone,

A few days ago i installed kitty alongside my Konsole terminal to get to know it a bit better(kitty). For some reason some shortcuts work only with the right shift key but not the left shift key. For example to open a new kitty window inside the OS window l_ctrl+ l_shift+enter does not work only l_ctrl+ r_shift+enter. On the contrary l_ctrl+ l_shift(or r_shift)+w to close a kitty window works with either. I have Fedora 41 with KDE. Any ideas as to why this might be happening or how can I fix it?

Run kitty with --debug-input and you will see what the OS is actually sending kitty when you press those keys.

This is the output when I try to use the default ctrl+l_shift+enter

That is just showing you pressing ctrl and shift not a full shortcut. Press teh full shortcut that is not working.

Okay I tried it again. The first screenshot is the regular shortcut and the second is when I am using the right shift key.

There is no press event for an enter key being delivered to kitty at all. So whatever your issue is, it is in a layer below kitty. Check your keyboard layout and IME subsystem settings.

Thank you I will look at those and if I find an answer I will post it back.

@kovidgoyal I have an update. After some more testing I discovered that the default shortcut of L_CTRL + L_SHIFT + ENTER creates a new window but only after I release the L_CTRL key first. So essentially it is upon the L_CTRL release that the default shortcut works. Below I am attaching the kitty --debug-input with the release of the L_SHIFT key. Any idea why this might be happening? I am not familiar with the inner workings of keyboard layouts so I don´t know exactly where to start investigating but if pointed at I can try looking into it.

According to the debug output the release event for L_SHIFT is last, after the release events for the other two keys. Sadly the keyboard handling space in Linux is an absolute clusterfuck of half baked and incompatible solutions, by the dozen, so I cant really tell you where to look other than start by disabling any IME and then set the keyboard layout to astandard us 101 and then look for any system level key mangling software thats running.
