#23 Toolbox tools should have keyboard shortcuts

[Ryan Carsten Schmidt]

Photoshop has handy keyboard shortcuts for switching to different tools, but I haven't been able to find any such keyboard shortcuts in Paintbrush 2.5. I'm using Paintbrush as a low-resolution icon editor, and I'm spending half my time moving the cursor from my document to the toolbox and back again as I switch back and forth between the eyedropper and the pen or line tool. It would be so much easier if I could leave the pen or line tool selected, and press and hold the Option key to temporarily switch to the eyedropper to pick up a new color without needing to move the cursor away from my document to do it.
