A weird thing I do that I love...
I make pressing the Caps Lock key act as a Backspace. It's on the home row of the keyboard and I make typos! I use it all the time.
I've seen some people remap Caps Lock to a 'Cmd+Option+Shift+Control' key and then use that as another layer of keyboard shortcuts. They call this the Hyper key. But I make typos way more often than I want keyboard shortcuts that aren't already available to me so I think Backspace is better.
Karabiner Elements is the app for this on Macs. Gnome Tweaks will do this for you on Debian/Ubuntu. SharpKeys on Windows.
