touchDown() with keyevent(), how to hold down 'w-a-s-d'

I can't seem to figure out a way to use the hotkeys in LDPlayer, i'm trying to literally press 'A' to walk left using the physical keyboard.

sending:

keyevent(29)

works....

but it only sends it once..

i need it to be able to hold it down like touchDown() works so I hold down the 'a' key for a certain amount of time so i can use it to walk directionally.

anyone have any suggestions? or Ankulua can we please implement a timeout option for sending keyevent() please.
