Blender Keyboard Shortcut Explorer
I’ve been learning Blender on and off, and one thing I picked up early is that keyboard shortcuts are essential if you want to work fast. Memorising them is tough — most of the cheat sheets and keyboard layouts floating around aren’t up to date, so I’d usually end up searching through forum posts.
Last weekend I was messing around with Python in Blender and noticed you can access all the keyconfig data through their API. I exported it to JSON and had fun building an interactive HTML keyboard that displays every shortcut. It even updates live as you press modifier keys.

Because the data is pulled straight from Blender, keeping it up to date is much easier than maintaining a hand-made cheat sheet.
Edit: This prototype eventually grew into a full release with support for over 20 applications.
