Enabling Vi mode in tmux allows for using Vi commands and hotkeys when navigating through the window output buffer (entered by <ctrl-b> [).

1. Enter set-window-option -g mode-keys vi into .tmux.conf.

2. Restart tmux or reload .tmux.conf.

3. In window buffer, one can now use functions such as the following:

   • /<keyword> to search for occurrences of <keyword>; use n and N to move between matches
   • Use hjkl to move cursor around
   • Use gg and G to move to the top and bottom of the buffer, respectively
