What info should go in a SoM help file?

[HwitVlf]

I have wanted to make a downloadable guide to go with SoM for awhile and Diver suggested enabling the standard Windows F1 help popup in SoM's editors. I don't know if I'll have time to put together a decent help file but:

Does anyone know if the F1 key is already used in any of the editors?
What aspects were hard to learn when you started SoM?

I'm thinking IF,OTHERWISE explanation, and basic Event/Page controls, basic how to use Counter, and perhaps a basic explanation of damage calculations.

As far as I know the F1 key only does something in test mode in game.

If a different help file could pop up per editor that would be really nice. ‎  I think quick tooltips to explain every option on the screen would be nice, though really a searchable help database would probably be best for anything further. Like simple help documents similar to what youve already created could be searched for if possible.
