So I'm a lefty, which means that most of my keybinds are focused on the number pad over on the right of the keyboard. And as you may know, having the num lock button OFF actually makes those keys do different things. Additionally, holding down any one of those buttons, then toggling num lock off will result in that button acting like it's held down.
At least every other play session, I'll depress some combination of keys while I'm flying, which makes me dismount and plummet to my death, without fail. Quite funny, if I do say so myself.
Anyhow, list some goofy things you still accidentally do, despite knowing better.
