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:

Left click:
Simply tap the screen with a single finger where you wish to click.
Left double click:
Tap the screen twice in quick succession, precision and speed are important.
Left drag:
Press a finger to the screen and slide it.
Activate the keyboard:
Tap three widely spaced fingers to on the screen simultaneously. All three fingers must be on the screen at the same time. At first it helps to do this slowly.
Right Click:
Press one finger to an inactive portion of the screen, and tap with a second finger.
Right double click:
Press one finger to an inactive portion of the screen, and double tap with a second finger.
Right drag:
Press one finger to an inactive portion of the screen, and slide a second finger.
Vertical screen panning:
Press three fingers to the screen and pan them up or down.
