common button names naming standards?

[Jeff S. <jef...@gm...>]

I was downloading some remote codes and noticed a lot of the buttons
are named the same from remote to remote but not all.

Is there a nameing standard to follow?

some buttons I see common are as follows
POWER
MUTE
CH_UP
CH_DOWN
VOL_UP
VOL_DOWN
1
2
3
