EOSM script 1 (Toggler)

1m.lua

--[[ 	
	Simple (no menu, ie runs in the background) script to help control ML states to your ML favorite states using your buttons of choice, 
	for example the MENU, PLAY & INFO buttons on the EOSM work well.
	Note this is the EOSM version
	To use the script simply note the following sequences on an EOSM (but you can change these for other cameras):
		3+ sec press of screen = enter toggler interactive imode
		In imode [PLAY] and [MENU] will toggle back and forwards through your ML condition states giving you an on-screen message
		In imode [INFO] will set that condition and leave interactive mode.
		In imode pressing (most) any other key, eg [SET] (not [MENU], [INFO] or [PLAY]) will leave interactive mode and use that key as normal: but some keys don't work!'
	
	Change/set the preset table below and the chunks of script to your liking, but note the need to keep track of ML states as you move between 
	toggled conditions, eg change functions reset() & display_message()
	
	Version M1.19
