Mapping <M-;> doesn't work

[muniter]

Hello. Mapping <M-;> doesn't work. This is Alt-;

I use this without issue in the TUI, and also in other GUIs (fvim, goneovim). Tried launching it from the terminal and test the mapping but have no output.

What I mean by not working is that the Gui doesn't send it to neovim, meaning nothing happens.

Just noticed I really didn't give much information. Sorry.

Want to add that other alt mappings work correctly, I have the issue only with this one.

Using Linux, Arch, Wayland, SwayWM

Same for <Alt-=>

Gnvim was rewritten from ground up for gtk4, but this issue was still present. This was fixed in https://github.com/vhakulinen/gnvim/commit/6b2c8a07478f97e57de2bf8f634564c08b4cf6ad.

Regarding the = and ; keys, you might need to add shift key to your mappings (depending on your keyboard layout).
