The majority of interactions with the client while connected to a windows machine follow normal windows interface actions. This means windows must be scrolled with the scroll bars, rather than panned with a webos gesture. Thus, a lot of clicks, drags, and double clicks need to be sent. To make this as easy as possible, these commands are all simple gestures. The visible screen is 100% utilized for drawing the windows desktop, rather than buttons for clicking or bringing up the keyboard.

So, here are the important gestures:
