C-x o is a horrible default keybinding, given how often one needs it. From my first days of using Emacs, I remapped it to F-6, which was the keybinding in the DOS days, and still works in most Windows applications. > For this reason, I remapped my arrow keys to move around them. I don't have access right now, but on my work laptop I use a package that lets you use Shift + Arrow Key to jump between windows. Of course, if your minor mode uses those keybindings for something else (e.g. org mode), then it won't work. > I also have `Command + Left/Right` for cycling between buffers This is a good idea. I use C-M-[ and C-M-]. At some point I learned how to use the Hydra package and often use that for major modes I'm not too familiar with. No longer need to memorize (or make my own custom) keybindings.
