Q: Tmux autocomplete internal commands Does anyone know a way to autocomplete tmux internal commands?
For example, inside tmux I type bind-key + : then type ren... and expect to get rename-window or similar by pressing Tab.

A: Tmux will autocomplete commands when the entered string is unambiguous.
In the example you provide, renTab could complete to either rename or renumber. In order to have the complete work, you would have to enter an additional character to remove the ambiguity: a.
