basically have a counter:

PHP Code:

function onPlayerenters()
{
  settimer(0.05);
}

function onTimeout()
{
  if (keydown2(keycode("f"),true) && this.speed<this.topspeed)this.speed++;
  else this.speed-=0.25;
  settimer(0.05);
} 


I dont think I've used valid syntax for keydown2 but I can't remember what works and what not o_0, hopefully this will give you an idea on how to do it. But you could always post your script then one of us can examine it and tell you what the problem is lol , its most likely that you not having the script take a break after the key is pressed. So pop into your script

PHP Code:

sleep (0.05); 


after your speed increment statement
