Emacs Comment Toggle
Comment toggling is one of my most heavily used features of a text editor. When I recently switched from vim to mainly doom emacs, I was disapointed to find that there was no built in keybinding for comment toggling single lines or blocks. After some googling, I found a system that works for me.
Add this to your config.el. I use doom emacs, but this could be pretty easily tweaked to work with vanilla emacs as well.
Just press <leader> (in my case, space), c, then ; to toggle a line or block of selected lines between commented / uncommented.
