If you’re an Emacs user like me, and your workflow involves windows splitting, you will eventually get tired of using ‘C-x o’ to navigate around. This command cycles through all the windows in order.
WindMove to the rescue! Unless you’re using an ancient version of Emacs, you already have this set up and ready to use. With WindMove you can move around windows intuitively by holding down shift and pressing the arrow keys. Much better than repeating ‘C-x o’ over and over!
