Default G2 Changing the headphone button to control music playback

Hi all, hopefully someone can help me, I tried to do the change on my rooted phone from key 226 HEADSETHOOK to "key 226 MEDIA_PLAY_PAUSE"

Question is, my original line for key 226 HEADSETHOOK is formatted weird, it has no number sign and a few extra spaces stock. Do i replace it with key 226 MEDIA_PLAY_PAUSE, no number sign and no quotations? Do I mimic the spacing? Currently, this is what my headsethook looks like with the line before it and after it as well:
-------------------------------------------------------
# key 225 "KEY_BRIGHTNESSUP"
key 226 HEADSETHOOK

key 256 BUTTON_1
-------------------------------------------------------

Note how mine has 3 spaces between 226 and headsethook....should I make the new code replacing it like this?:
key 226 MEDIA_PLAY_PAUSE (there are 3 spaces between 226 and media)

And should I still skip a line after it?
