How to terminate a window in tmux? Like the Ctrlak shortcut in screen with Ctrla being the prefix.
& for killing a window
x for killing a pane
If there is only one pane (i.e. the window is not split into multiple panes, x would kill the window)
As always iterated, is generally CTRL+b. (I think for beginner questions, we can just say CTRL+b all the time, and not talk about prefix at all, but anyway :) )
