Keyboard Shortcuts?

I don't think anyone has requested this yet, but simple keyboard shortcuts would be immensely helpful and make this product even faster. If i could simply press "R" for rectangle, instead of having to find the icon. The quick entry tool is nice, but full keyboard shortcuts would be faster. At the very minimum, the ability to invoke the quick entry tool with a keyboard command would help greatly. (sorry if this already exists and i'm just not realizing how to use it).

Keep up the great work, this is by far one of the most useful pieces of software i've come across in the last few months!
