Vim Cursor

This is an example keyboard to demonstrate the power of layers and advanced key codes. The behaviour is simple:

• By default, keys act as expected.
• When the space bar is held, keys HJKL are remapped to move the cursor left, down, up, and right. The remapping is disabled when the space bar is released.
