I found a website provides a fundmantal shortcut key description:

http://www.seoconsultants.com/windows/tips/keyboard-shortcuts.asp

Keys for E-Mail
All shortcut keys are based on the U.S. keyboard layout. Keys on other layouts may not correspond exactly to the keys on a U.S. keyboard.

For keyboard shortcuts in which you press two or more keys together, the keys to press are separated by a plus sign, like this: SHIFT+F10.
For shortcuts in which you press keys one after the other, the keys to press are separated by a comma, like this: ALT, F, X.
