if cretain keys are pressed, play the next song

[GodForsakenSoul]

i'm trying to make a little script for a friend. here's the main idea:

dim $loop=1
while $loop=1
   if ???1 then
      send ("{MEDIA_NEXT}")
   elseif ???2 then
      send ("{MEDIA_PREV}")
   elseif ???3 then
      exit
   endif;i'm not sure why, but it does not bitch when i type it this way instead of putting endif after each thing =/
wend

as you can see, i managed to nail all the things that are sort of easy...

HOWEVER, i can't seem to make the following idea:

if shift+n_is_pressed then

send ("{MEDIA_NEXT}")

endif

i have no idea what i can do to make it work =/

also, while $loop=1 wend kind of thing is very cpu-consuming, however it's the only way i know to make the thing run untill i stop it.

i would also love suggestions on the topic of how to make it run forever without eating 99% cpu.

There are two solutions:

HotKeySet("+n","shiftn")
while 1
Sleep(100) ; You sleep a loop to make it CPU friendly
WEnd
Func shiftn ()
send ("{MEDIA_NEXT}")
EndFuncoÝ÷ Øêò¢ç붢YhÂ)à[a¢è!¶»-Æ޶׫jëh×6#include <misc.au3>
while 1
Sleep(100) ; Always sleep loops
If _IsPressed("10") And _IsPressed("4E") Then
send ("{MEDIA_NEXT}")
EndIf
WEnd
