One of the children on my Summer course was having 'problems' with 
animating a 'person'
to jump [ think "Super Mario"].

Well, I don't know what he is doing this weekend, but it took me all of 
15 minutes to knock together a basic walker-cum-jumper:

HOWEVER, there is a slight snag insofar as that having been bashing the 
left arrowKey, when I bash the up arrowKey (to generate a jump),
the character jumps, but then continues to execute the code stored from 
my pressing the left or right key for far too long than is

The same thing happens if I press the left key repeatedly, then the 
right key once.

SO, what I need is some sort of INTERRUPT code so that when I press a 
new arrowKey all previous information fed by my key bashing gets lost.
