Go Back To The Previous Window
vim
Written March 18, 2019
When working with multiple files, you may have one or more window splits
open. You may even be moving back and forth between two in particular --
perhaps if you are iterating on a test and its implementation. You can move
back to the previous window using Ctrl-w Ctrl-w. This is the same as
hitting Ctrl-w w.
Once you've moved back to the previous window, the window you were just in
is now the previous window. That means you can keep hitting Ctrl-w Ctrl-w
to toggle back and forth.
See :h ctrl-w w for the exact command and :h ctrl-w for more on window
commands.
