Dota – Greevil consumable items: usage and meaning

I suggest you to take a look to file <Steam>\steamapps\common\dota 2 beta\dota\resource\dota_english.txt, it contains all language definitions.

If you search for DOTA_Tooltip_Ability_item you should find a section of items tooltip definitions.

I would suggest that you bind the item hotkeys to F1-F6, or the control groups to those and have 1-6 be for items. Of course, that depends on your overall comfort and preference, but it is a significant improvement over having to use the numpad.

The only downside is that F1-F6 are already bound to spectator actions, but those can probably be binded over to the numpad without causing you too much duress.
