SwitchToMode "Scroll" when scrolling with the mouse?

[celynw]

Is there a way to automatically switch to SCROLL mode when scrolling with the mouse, or make bindings to mouse events (specifically the scroll wheel)? I'm guessing no because I can't find any such reference in the documentation or in issues/discussions... more context below.

For scrolling, I believe the dedicated SCROLL mode is superior to the NORMAL mode. So I've made some bindings like these, which work wonderfully:

bind "Shift Up" { SwitchToMode "Scroll"; ScrollUp; }
bind "Shift Down" { SwitchToMode "Scroll"; ScrollDown; }
bind "Shift PageUp" { SwitchToMode "Scroll"; PageScrollUp; }
bind "Shift PageDown" { SwitchToMode "Scroll"; PageScrollDown; }

I also bind Escape to return to normal mode, which also scrolls to the bottom where the prompt is.

bind "Enter" "Esc" { SwitchToMode "Normal"; }

The mouse wheel will scroll the screen properly in either mode, but won't automatically switch modes. So, pressing Escape when scrolled up but in NORMAL mode will return the scroll position to the bottom, but will also send an escape sequence to the terminal.

So then pressing the up arrow won't go through my history, but instead print the keycode to the terminal:

$ [A

I'm looking for this same thing. It's been a while since I've used tmux, but I'm pretty sure this is how it worked. With zellij, the muscle memory is killing me because I'll scroll back to somewhere that I'm interested in and then expect to be able to perform an action in scroll mode like scrolling line or page-wise, but instead, it just scrolls me all the way back to the prompt. I want mouse wheel actions to actually put zellij in scroll mode.
