WASD - Move
E - Interact (Open doors, read books, buy items, etc.)
F - Attack (in the direction you are facing)
Q - Use Item (read scrolls, if you have one)
Ctrl - Charge Magic
Tap Ctrl quickly - Next spell (if you have one)
Release Ctrl (with magic charged) - Fire Magic
Shift - Run
Right Click (standing still) - Block
Right Click (while walking) - Dodge roll
Right Click (while running) - Power Dodge roll
These are the current commands in the game, the demo version does not contain running or blocking based commands. Also; these will be remapped in the future, since casting magic and running use the same key right now, which feels a bit odd.
