JUMPING WHILE RUNNING

Alright, if it is possible for RM2K3... I'd like to be able to be running, and while running, I would like to be able to run over an event and press the key (we'll say the space bar for now) and have my character jump. My character will jump if I stop on top of the event of course, but I don't want to have to stop to be able to do it. Also, I don't want it to be set to happen if I collide with it.

Uhh.. if you're still not clear on what I'm asking (I'm pretty bad at explaining things)

Character is running, passes over an event, press button while on event but still moving forward, character jumps forward. That's what I want to happen.

Oh, and I'd also like to make it where I can continually run forward without me having to push any arrow keys. And still be able to interupt it. (Jumping and auto-starting things are my down point with events, which are pretty important unfortunately)
