Yeah, that's too be expected since getting 2 keypresses from one keypress would be bannable
Actually, according to the European CS community it is not... had no blue response to my own query but responses regarding the G-15 show that providing there are no delays involved they have no probs with 1 physical key = multiple keypresses, EVEN in a sequence

so those using G-1 = "/cast [target=focustarget,harm] Lightning Bolt" are well within the acceptable use policy

but I can't find the thread now (will still post be take what I just said with a pinch of salt until I get a blue response)
