Multi-Touch with the Pull Tool
Select and drag geometry to change it.
Immediately drag to pre-highlight geometry. You can also touch in white space and drag to pre-highlight. This shows you what will be selected before you select it.
After you pre-highlight geometry, tap with a second finger or raise the first finger to select the geometry.
Press the spacebar to enter dimensions for an offset face, just like you can when you use a mouse instead of multi-touch.
Starting on whitespace, drag with one finger, then hover over an edge and double-tap with another finger to query select through the available edge loops. This behavior is the same as a simple double-tap.
Starting on whitespace, drag with one finger, then hover over a face and triple-tap with another finger to select all the faces of the body. This behavior is the same as a simple triple-tap
