用于在 Xcode 4 中查找当前选定文本的键盘快捷键
在 Visual Studio 中（多年来我的主要用途），我可以按 Ctrl+F 立即搜索文本插入符所接触的标识符或字符串，或者如果我有选择，则搜索当前选定的文本。我可以按 Ctrl+Shift+F 搜索整个项目、解决方案或其他文件集。我喜欢这个。
在 Xcode 3.* 中——我近年来的主要挤压——我可以按 Cmd+Opt+F 立即搜索当前选定的文本，然后按 Cmd+Opt+Shift+F（有点少，但可行）来搜索整个项目。与 VS 方法相比，我不太喜欢这种方法，因为我首先必须选择一些文本，然后搜索它，而不是如果我没有选择任何内容，IDE 会自动为我获取当前标识符。但没关系。
现在，在 Xcode 4 中，我注意到有一个 Cmd+E 快捷方式可以使 Xcode“使用选择进行查找”。但它……嗯，这很糟糕。显然，它所做的就是复制当前选择并将其粘贴到查找框中。它不显示查找框，因此如果当前未显示查找框，则 Cmd+E 没有可见效果。 Cmd-E 实际上并不调用搜索——它仅复制文本。因此，现在搜索标识符变成了一个三步过程：选择标识符，按 Cmd+E，按 Cmd+F（或 Cmd+Shift+F 用于项目范围搜索）。
IMO，Xcode 4 的三步过程比 Xcode 3 的两步过程更糟糕，而 Xcode 3 的两步过程又比 Visual Studio 的一步过程更糟糕。
我的问题：鉴于用户界面效率的下降以及最近的国际事件，世界是否正在走下坡路，很快一切都会以激烈的灾难结束，剩下的少数人类将被迫重新输入战争与和平 每次他们想要搜索标识符时？
In Visual Studio—my main squeeze for many years—I can press Ctrl+F to immediately search for the identifier or string that my text caret is touching, or else the currently selected text if I have a selection. I can press Ctrl+Shift+F to search the whole project, solution, or other file sets. I like this.
In Xcode 3.*—my main squeeze in recent years—I could press Cmd+Opt+F to immediately search for the currently selected text and Cmd+Opt+Shift+F (a bit of a handful, but workable), to search throughout the project. I liked this a bit less than the VS approach because I first had to select some text, then search for it, rather than the IDE automatically picking up the current identifier for me if I hadn't selected anything. But it was fine.
Now in Xcode 4 I notice that there is a Cmd+E shortcut that makes Xcode "Use Selection for Find." But it... well it sucks bad. All it does--apparently--is to copy the current selection and paste it into the find box. It doesn't show the find box, so if the find box isn't currently shown then Cmd+E has no visible effect. Cmd-E does not actually invoke the search--it only copies the text. So now searching for an identifier becomes a three step process: select the identifier, press Cmd+E, press Cmd+F (or Cmd+Shift+F for project-wide search).
IMO, Xcode 4's three-step process is worse than Xcode 3's two-step process, which is worse than Visual Studio's one-step process.
My question: In light of this falling UI efficiency along with recent international events, is the world just going downhill and soon all will end in a fiery apocalypse in which the few remaining humans will be forced to retype War and Peace each time they want to search for an identifier?

ughoavgfhw 提供了正确的答案（上面）。在
所选文本上使用Cmd+E开始搜索该文本。然后立即输入 Cmd+Shift+F 在整个项目中搜索文本点击 enter 的所有实例。这是相当快速、一致且明智的。它不像 Visual Studio 的单笔查找/在文件中查找那么直接 - Xcode 需要两笔而不是一笔 - 但就我个人而言，额外的步骤并不困扰我。
ughoavgfhw offered the correct answer (above). Use Cmd+E on the
selected textto begin searching with that text. Then immediately type Cmd+Shift+F to search the whole project for all instances of the text hit enter.This is quite quick, consistent, and sensible. It's not as immediate as Visual Studio's single-stroke Find/Find-in-Files—Xcode requires two strokes rather than one—but personally the extra step doesn't bother me.
对我来说，最好的选择是进入 Xcode> 首选项> 键绑定，然后在过滤器中输入“在工作区中查找选定的文本”并将其绑定到您所需的键，我将其绑定到 Shift+Ctrl+Option+Cmd+F
注意：I我使用的是 Xcode 版本 10.3
For me the best option was to go under Xcode>Preferences>Key Bindings and in Filter type "find selected text in workspace" and bind it to your desired key, I binded it to Shift+Ctrl+Option+Cmd+F
Note: I am using Xcode version 10.3
迟到了，但有人可能会受益：
我使用免费的 BetterTouchTool 并为丢失或尴尬的 Xcode 快捷方式定义自定义快捷方式。您可以将多个操作附加到自定义快捷方式，我已将 Cmd+E - Cmd+Shift+F - Enter 分配给鼠标中键，它让我只需单击一下即可在工作区中搜索选定的文本。您可以将相同的操作分配给键盘快捷键，尽管我更喜欢使用鼠标按钮来完成此任务，因为我也使用鼠标进行文本选择。
ps：BTT 让您可以选择在哪个应用程序中应用您的快捷方式，或者您可以将自定义快捷方式设置为全局，我也觉得这很方便。
Late to party but someone might benefit:
I use the free BetterTouchTool and define a custom shortcut for missing or awkward Xcode shortcuts. You can attach multiple actions to your custom shortcuts, I have assigned Cmd+E - Cmd+Shift+F - Enter to middle mouse button, it lets me search the selected text in workspace with a single click. You can assign the same actions to a keyboard shorcut though I like mouse buttons better for this task because I also do the text selection with mouse.
ps: BTT gives you the option to select in which application your shortcut will apply or you can make your custom shortcuts global, which I also find handy.
