在打开的文件之间来回导航: ⌥⌘← ⌥⌘→

Command⌘alt shift T:在项目树中显示当前编辑的文件。

我不知道是否每个人都知道这一点，但当我了解到我可以使用“代码折叠”并通过单击想要折叠的代码附近的灰色区域来隐藏我不想查看的嵌套函数时，我很高兴。

很难解释……

Cmd+Option+O to open a file in a separate window. Can configure Tab to always indent. I frequently use it to indent an entire file. Ctrl+Arrow keys to move between camel case words. If you have OneTwo, you can move from One to Two with Ctrl+Right arrow. You can use emacs bindings, there's even kill ring! I use the Ctrl+w and Cmd+C together when I need to copy two different pieces of text. In the documentation browser, you can restrict your searches to a particular library, e.g., just iOS 4.2 library. This helps me focus on API available only on a particular iOS/Mac version of the SDK. Cmd+Shift+A to build and analyze.

触控板:

向上滑动三个手指-在头文件和源文件之间切换，这比Cmd + Opt + Up更容易; 向下滑动三个手指-在选择类或方法时切换声明和定义，目前发现这两种; 向左滑动三个手指-返回(Cmd + Opt + left); 向右滑动三个手指-前进(Cmd + Opt +右);

用Xcode 3.2.5测试。

如果高亮显示搞砸了，如果你的变量没有高亮显示或其他任何东西，只需执行⌘-A⌘-X⌘-V，这将全部选中，剪切和粘贴，所有高亮显示将被纠正。所以只要按住⌘，然后按A X V。
