When pressing CTRL + B, (or another arrow key) I am able to resize the current pane of one step only.

I was expecting to be able to resize the pane progressively by keeping the prefix and arrow keys pressed, however this is not the case because the key is then intercepted by the command line again.

How can I modify the .tmux.conf in order to behave correctly? I guess it has to do with something like changing the behavior of the prefix key, right?

EDIT

I am using zsh as my default shell. My .tmux.conf contains only the following (possibly unrelated) commands:

set -g mouse on        #For tmux version 2.1 and up
setw -g mode-keys vi

The arrow keys to resize repeat by default (unless you've changed them), but you need to let go of the prefix key. So you need to press C-b Left then keep pressing Left.

If you hold down the arrow key rather than pressing it several times then it should work so long as repeat-time is longer than the system key repeat interval.

  • Unfortunately, it's not my case. I am adding more info to the question. – aretor Mar 27 '20 at 12:04
  • Did you try increasing repeat-time? Try tmux set -g repeat-time 10000 and see if it works, then reduce to find when it stops working. Make sure you are releasing the prefix though. – Nicholas Marriott Mar 27 '20 at 12:25
  • It works now, despite I have to press the combination C-b + arrow twice, to activate the resize. The first time it's like the input is not captured. – aretor Mar 27 '20 at 20:38
  • Are you sure you are pressing C-b then Left, not C-b C-Left? Make sure you release ctrl and b before pressing Left. – Nicholas Marriott Mar 27 '20 at 20:43
  • If I do as you say, I just switch between panes. Am I missing something? – aretor Mar 27 '20 at 21:00
