mouse mode on, scroll acts like arrow up and down

[flynxea]

Could tmux be configured as Byobu when using mouse? I set mouse mode on, copy and paste works well. But when I scroll the middle key of the mouse, it acts like arrow key up and down, scroll the command history.

I just want it to be the style of Byobu, when scroll mouse middle key, enter copy mode. I searched in the internet, someone said that it's because the terminal send arrow up/down when scroll mouse.
But it works well when I use Byobu with the same terminal. And my Byobu bridged with tmux instead of screen.

thanks.

Hello @flynxea 👋

I'm sorry I don't know Byobu nor MobaXterm.

I also don't use the mouse with tmux.

From what I can see, the default bindings for MouseDown3Pane are rather complex and I don't know how to advise you.

$ tmux lsk | grep MouseDown3Pane

Searched form Google and tried everything, seems this works. Don't know why. set -g terminal-overrides 'xterm*:smcup@:rmcup@'
