Reaching for mouse and doing the clicking ( which need to AIM, TARGET and SHOOT (click) sometimes will slow down a simple task, where we could actually press a single key on the keyboard, and the TAB key to move the cursor among the controls. It will be faster and comfortable for the user.

John's idea is simple and perfect! But I need to mention one point on keyboard
input for those controls:

Combox, Radio Button: Use Arrow to select your choice.

Check Button: Press {SPACE} to alter your choice.

You still easy to use those controls by keyboard.
