以下是For Mac OSX用的快速鍵
1. Apple Logo
快速鍵 : Option-Shift-K
2. Zero Brightness～馬上把螢幕亮度切至無亮度
快速鍵 : Control-Shift-Eject
Note. Instantly turn your display off without logging out from the system.
3. Adjust Volume Bar～微調音量，可將原本一格的音量調整再細分為四等份，作四分之一的微調
快速鍵 : Option-Shift-F4 / Option-Shift-F5
Note. Increase/decrease your volume bar by a quarter each time it's invoked. This is particularly useful for fine tuning Mac with bombastic sound system.
4. Double Buffer～Control-K可剪下游標後方的整段文字(不需反白)，Control-Y可將用Control-K剪下的文字貼上，類似Copy & Paste的功能
快速鍵 : Control-K (Kill) and Control-Y (Yank)

5. Home and End～將游標移至文章的首字及尾字
快速鍵 : Control-A (Home) and Control-E (End)
Note. This is pretty much the substitution for Windows button HOME and END. Pressing Command-← or Command-→ performs the same action.
6. Delete and Backspace～就是Delete 跟 Backspace的快速鍵，這個Delete(Control-D)的快速鍵筆使用筆電時可按的fn+delete好按得多
快速鍵 : Control-D (Delete) and Control-H (Backspace)
Note. In Windows, we've got two buttons for this : DEL and BACKSPACE. You can use Fn-Delete to perform forward deletion while the button Delete acts as Backspace.
