Fix keyboard shortcuts to fully work with more layouts than QWERTY

[HarHarLinks]

Steps to reproduce

I'm using Linux with a German QWERTZ layout in hardware and software. I tried all shortcuts the menu presented me with on my platform and in this order.

1. Ctrl+/ does not work on QWERTZ Improve keyboard shortcuts toggling space panel, room list, right panel #21049 (comment)
2. Ctrl+> does not work on QWERTZ as > is produced by Shift+<
3. Ctrl+Shift+U does not work and starts unicode composition instead, see also More hotkeys / keyboard shortcuts #3232 (comment)
4. Clear room list filter field does not apply anymore with new spotlight Clear room list filter field does not apply anymore with new spotlight #21068
5. Ctrl+` does not work on QWERTZ Ctrl+` is a horrible key for keyboard shortcut and does not work on mine #19694 and is likely a deadkey and breaks macOS cmd-` as a keyboard shortcut on macOS hijacks the OS shortcut for switching between windows of an app #14381
6. Ctrl+; as introduced by Keyboard shortcut to open the sticker picker matrix-org/matrix-react-sdk#7985 does not work

Most of these do not work because while they are basic keys on QWERTY, they require combinations on different layouts. For example / is present on QWERTY with a single keypress, but on QWERTZ it requires Shift+7 to type it.

Untested

• Ctrl+Alt+Up/Down idk it just does nothing but maybe testing wrong
• Ctrl+D
• Ctrl+E

Outcome

What did you expect?

What happened instead?

do not work. I am certain that with more international layouts, more issues arise.
