keyboardxcode
I have an Xcode window open with many tabs. I want to open a file through Quick Open (⇧⌘O).
When I decide to close the Quick Open menu and also close the current tab that I'm on, I'll press Esc to close the Quick Open menu, and then press ⌘W to close the tab. However, sometimes I make a mistake and press ⌘W on the Quick Open menu, which causes the entire Xcode window to close instead.
Is it possible to prevent this behaviour? Maybe prevent ⌘W from doing anything when Quick Open is open?
With the new macOS Sierra, it is possible to use the keyboard shortcut ⌘⇧T to reopen the last closed tab – à la Chrome and other browsers.
The previous shortcut, ⌘Z, allowed you to reopen closed tabs, but was more of a "general purpose" button which allowed you to reopen closed tabs, but also to undo other actions. The new shortcut is specifically meant to reopen closed tabs.
Left column in Xcode is called Navigator. You can show/hide it with ⌘+0 (Zero), or in the upper right window corner, see image:
In the Navigator there are dfferent tabs (Project Navigator, Symbols Navigator etc.). To see list of files in Your project You need to select Project Navigator or press ⌘+1.
To open file in current tab, single click on it in Navigator. If You double click the file, it would open in new window/tab. You can change the behaviour of double click in Preferences... -> Navigation -> Double Click Navigation.

Here's how you unset the keyboard binding for
Close Tabaka⌘+W.+buttonApplicationdropdown selectXcodeClose Tabfor theMenu TitleThis un-maps
⌘+Wshortcut in Xcode app completely. After this you are free to remap the⌘+Wkey bindings in Xcode.In my case I like
⌘+Wto close the document so from Xcode -> Preference -> Key Bindings I have these changes (In your case you can bindCtrl+⌘+WtoClose Tabinstead and leaveClose Documentunmapped).
