Here's a txt version of the "Introductory SketchUp Notes" I provide my students - these are the "default" shortcuts - you can easily change them to be whatever you want - there's also some additional information listed here as well - maybe this will help (& I hope I'm not infringing on any copyright laws by posting this):
