Xcode 6中的箭头键不起作用 [英] Arrow keys in Xcode 6 not working

问题描述

我在OS X Yosemite上遇到了最奇怪的Xcode 6问题.由于某种原因，我无法再使用向左和向右箭头键在源代码中进行导航.而是会发出系统提示音.向上和向下箭头可以正常工作.

I have the weirdest issue with Xcode 6 on OS X Yosemite. For some reason I can't use the left and right arrow keys anymore to navigate within my source code. Instead, the system beep sound would come up. Up and down arrows work fine.

恐怕这可能与我对按键绑定的摆弄有关.尽管仅更改了用于块(de)缩进的内容(最初是CMD + [，更改为TAB)，所以据我所知，箭头键根本不会受到影响.

I'm afraid it could have something to do with my fiddling around with the key bindings. In only changed the ones for block (de)indentation though (originally CMD+[, changed to TAB), so in my understanding the arrow keys shouldn't be affected at all.

推荐答案

我能够通过运行使其再次工作

I was able to make it work again by running

defaults delete com.apple.dt.Xcode

在终端中，然后重新启动Xcode.

in the terminal and then restarting Xcode.
