I stumbled upon this issue when I first started using vim, and it was a nightmare trying to remember all those key bindings. I found this incredibly handy cheat sheet on GitHub called 'vim-cheat-sheet' that breaks everything down into categories like navigation, editing, and commands. It’s color-coded and super easy to read, which saved me a ton of time. Another place I check is the official vim documentation, but let’s be honest, it’s a bit dense. For quick reference, I also love the 'Vim Adventures' game—it’s a fun way to learn while playing. If you’re into physical copies, there are printable versions floating around on sites like Reddit’s r/vim community.
