下面就簡單的介紹下Android Studio的幾個快捷鍵的使用:
NO.1 Ctrl+N 可以快速的查找你需要打開的類，當你輸入類名的時候具有自動補全功能！
To open any class in the editor quickly, press Ctrl+N (Navigate | Class) and start typing the name of the class. Choose the class from a drop-down list that appears.
You can open any file in your project in a similar way by using Ctrl+Shift+N (Navigate | File)
NO.2 Ctrl+Space 自動補全功能 ，相當於eclipse中的Ctrl+/
The Code Completion feature lets you quickly complete different kinds of statements in the code. For example, start typing a class name and press Ctrl+Space to complete it. When multiple choices are available, they are shown in the lookup list.
NO.3 Ctrl+Q 快速的查看的 類，函數的 文檔問信息描述
To quickly see the documentation for the class or method used at the editor's caret, press Ctrl+Q (View | Quick Documentation).
NO.4 Ctrl+B 導航顯示相關關聯信息。可以按住Ctrl 點擊方法進入到實現類方法中
To navigate to the declaration of a class, method or variable used somewhere in the code, position the caret at the usage and pressCtrl+B. You may also click the mouse on usages with theCtrl key pressed to jump to declarations.
Ctrl+D 備份選中行的信息（Xcode 中始終沒找到。有哪個大神知道給我留言萬分感謝）
Ctrl+D in the editor duplicates the selected block or the current line when no block is selected.
