Tmux shortcuts

After my Vim keymappings cheatsheet, here are my current settings for Tmux. Again, I published several blog posts related to my Tmux settings in the past.

Initially I defined a second prefix key, and then I decided that C-b is perfectly good for me, and I rather add a new “hot key” in the name of “Meta” (Alt). Ubuntu relies on the Super key for its mappings, while the Ctrl key is used by Vim, Irssi, and many other of my CLI software. The Alt key is pretty handy for me, it reminds of my Emacs time and it does not interfere with other environment that I know or use regularly (beside folks using both the Ctrl and Alt key in some Vim plugins).

Compared to Neovim, my requirements are even more minimalistic since I don’t use any extra plugins or frameworks. In what follows, I only show what I added to my .tmux.conf file.
