tmux: Meta-<Arrow> and Mouse Issues

Hi,

I’m using terminus with the default “WSL / Ubuntu-18.0.4” profile and have the following in my tmux.conf file:

# Use Alt-arrow keys without prefix key to switch panes
bind -n M-Left select-pane -L
bind -n M-Right select-pane -R
bind -n M-Up select-pane -U
bind -n M-Down select-pane -D

# Enable and Disable Synchronize Commands to All Panes
bind -n M-a setw synchronize-panes on
bind -n M-o setw synchronize-panes off

# Enable mouse control (clickable windows, panes, resizable panes)
set-option -g mouse on
setw -g -q mouse on

While [Alt+a] and [Alt+o] (2nd section) work just fine [Alt+<Arrows>] (1st section) do not work.

Also, my mouse is almost not usable. I cannot select + copy temp plus I cannot select panes.

All of the above work just fine with Windows default WSL terminal and some other ones.

Any idea what it can be wrong?

Thank you Dimitrios

Faced with same issue. I could not send Meta (Alt) to tmux in tabby. however it still works on default terminal app in Window and Ubuntu. Enable “Use Alt key as the Meta key” didn’t work

Same here, alt+arrow cannot work under tmux.
