Additional notes

Copied from #1884 (comment) to get it more visible.

[2026-02-19 10:42:47.029840] [vt.input] Sending Shift|Control|NumLock "N" Press.
[2026-02-19 10:42:47.030045] [vt.trace.sequence] control U+07 (Bell, Alert)

If NumLock is off then things work again but I think, by default, keyboard shortcuts should be NumLock/CapsLock/ScrollLock agnostic. Particularly as I don't have a button on this keyboard to turn off NumLock so I had to work out how to toggle it from software :-)

[christianparpart]

Okay, sorry for the experience, I really thought I wasn't touching too much lately. Root-ause, working on improving kitty keyboard handling, but i broke NumLock along the way (in the frontend layer, actually)...

I'm fixing it right now.

[cqexbesd]

no problem - its still the best terminal emulator I have used - and we all have bugs - you just don't see mine ;-) I am very grateful for all the effort you are putting in.

I have built master and ctrl-shift-n still isn't working. I don't have time to investigate now - hopefully tomorrow - but briefly:

and its prints an N,

[christianparpart]

@cqexbesd should be back working now, sorry for that and for the delay, I am apparently too busy working on Endo lately 😆

[cqexbesd]

just built from master now (0.6.3-master-138e0ac4) and still not working :-( I reset my config so running with defaults and it doesn't change anything.

looking at the commits I can't see a fix so maybe you missed merging something? of course me being blind is also quite possible.

if there is anything I can do to help debug just say the word. tbc I'm not using Wayland, just regular X.

[christianparpart]

wow. i fixed it for me. hmm.. let me digg deeper.

[christianparpart]

@cqexbesd I've just installed tcsh on my Fedora and tried contour latest master with tcsh. Numlock on produces numbers, numlock off produces moves. 🤔

[christianparpart]

ok my bad, i wasn't reading carefully. hold on....
