Simple enough to decrease the variable when a key is not being
pressed. Taking Sakari's example...

if ( keypressed() )
	variable++;
else
	variable--;

or if you need to accelrate faster..

int acc=5;

if ( keypressed() )
	variable+=acc;
else
	variable-=acc;

Are you picking up what I'm putting down?
Hope this helps.
