I dunno how many times I've answered this question, but I guess I'll do it again.
WASD - movement. Take a guess as to what's what.
LMB: Jump
RMB: Spin Dash
E: Fire a ring. Dunno whether it's secondary or not, I've not played a netgame since v1.0.8.
Q: Light dash, if applicable
X: When I remember to put it in autoexec.cfg, that'd be switching between first-person (Match and when I feel like it) and third-person (any other time).
