[Sketchbook Pro] How do you select multiple objects?

[rsq_b]

This seems like such a stupid question, but I can't figure it out: when using a select tool (like the rectangle select or lasso select), how do you select multiple items? In Photoshop, this would be done by holding down the select key to add to current selection to the previous selection.

You can't do it. Selections are a little bit limited in SBPro. It doesn't have the full scope of Photoshop, etc. The price of being so nimble perhaps?
