Alt+[] also triggered by Ctrl+PageUp/PageDown

[jovandeginste]

Basic information

zellij --version: 0.36.0
stty size: 53 117
uname -av or ver(Windows): 5.15.0-71-generic #78-Ubuntu (and other)

List of programs you interact with as, PROGRAM --version: output cropped meaningful, for example:
Tilix version: 1.9.5 (but other terminal emulators show the same behaviour)

Further information

1. start a fresh instance
2. create multiple panes
3. use ctrl+pageup and ctrl+pagedown
4. see the layout change as if using alt+[]

This is annoying since I use ctrl+pageup/pagedown to switch between buffers in Neovim.

Thought this might help with debugging:

This also happends on Ctrl/Alt + Insert and Ctrl/Alt + Delete

[rnovacek]

Shift + PageUp and Shift + PageDown have the same effect and cannot be remapped (I have raised #2673 about it).

[tbottomparallel]

Also Alt PageUp and Alt PageDown trigger the layout changes, and cannot be unbound

and in a similar vein Ctrl Alt Arrow and Alt Shift Arrow and Ctrl Alt Shift Arrow all behave like Alt Arrow

Same problem here: on linux you learn pretty soon to Shift PgUP/PgDown to scroll through the terminal.

If it cannot be mapped to scroll up/ down (see #2934), at least avoid making it mapped to something else: muscolar memory is hard to remap, but having it triggering other changes is really disappointing.

This bug raise frustration in daily usage of a your great project, please don't forget about user experience of linux nerds, that is likely one of your major base.

Yes, I wouldn't mind if the key combination did nothing. But when it suddenly changes the layout of my panes, which were perfect they way there were. Arrgh. And I can't restore then back again.

Problem is though, I have no idea where this mapping is coming from. Or what function it maps to even. I have tried searching github, but can't find anything relevant.

I think the first step to solving this issue is knowing exactly what happens when you push Shift/Ctrl/Alt PageUp/PageDown.

If somebody could point me to a code reference where these mappings are defined, that would be a huge help.
