How to disable pane-switching of Ctrl-{h,j,k,l} on tmux? #361

Closed rikkiemariko closed 9 months ago

rikkiemariko commented 10 months ago

I'd like to use Ctrl-{h,k} as linux terminal commands (Ctrl-h to delete a letter, Ctrl-k to delete-to-the-end-of-line) when I'm in a tmux pane.

So, I set the navigation command as Alt-{h,j,k,l} and they all work perfectly. BUT Ctrl-{h, j, k, l} switch the pane Tmux-to-Tmux and Tmux-to-Vim instead of working as linux commands inside the current pane. (Ctrl-{h,j,k,l} doesn't switch panes on Vim-to-Vim and Vim-to-Tmux as I expect.)

How can I disable pane-switching of Ctrl-{h, j, k, l} on tmux?

My .tmux.conf (I'm using mac, so Alt-{h,j,k,l} look weird.)

It looks like you've got both the TPM tmux plugin installation, and the manual configuration (is_vim=... and the bind-key -n '˙' if-shell "$is_vim" 'send-keys ˙' 'select-pane -L' # <A-h>), as well as non-tmux-navigator config bind-key -T copy-mode-vi '˙' select-pane -L # <A-h>.

To make this work, I'd suggest the following:

How can I "remove the TPM installation in my tmux.conf"? I modified my .tmux.conf as below, and I ran "tmux source ~/.tmux.conf" but nothing has changed.

I think you'll need to restart the tmux server (exit all tmux sessions and then restart) for the change to take effect as the server will still have the TPM code loaded.

I'm going to close this issue now as this seems to be more of a config issue than an actual problem with the plugin, but hopefully the notes above can get you back to working.
