[visual-studio-code] Visual Studio Code Tab Key does not insert a tab

I'm using Visual Studio Code as my code editor. I did a search on google but wasn't able to find anything about my issue.

The issue is simple, pressing ? Tab in the editor does nothing. I'm expecting it to insert 4 spaces.

Anyone know what I can do to get ? Tab working like expected?

Try CTR + M it will work like before.

As of December 2018 on macOS Mojave 10.14.2 using VSCode 1.29.1 the default keybinding for 'Toggle Tab Key Moves Focus' is set to Command+Shift+M. If you got stuck with this, using that key combo should fix the issue.

Do Command+K Command+S to pull up the Hotkeys Settings and then search for Toggle Tab Key Moves Focus or editor.action.toggleTabFocusMode if you want to change the key combo.

Not sure what operating system you're on, but there was a known issue with the tab key on one of the more recent releases of VS Code for Mac OS X. The bug has been fixed in the latest release (0.10.9).

On Mac OS X, you can check for the latest update by opening VS Code and then going to [Code > Check for Updates].

All the above failed for me. But I noticed shift + ? Tab worked as expected (outdenting the line).

So I looked for the "Indent Line" shortcut (which was assigned to alt + ctrl + cmd + 0 ), assigned it to tab, and now I'm happy again.

I also use tab to accept snippet suggestions, so I've set the "when" of "Indent Line" to editorTextFocus && !editorReadonly && !inSnippetMode && !suggestWidgetVisible.

For those of you not about that space bar life (- _ - )( - _ -)

1. Keybinding for ? Tab isn't set to anything so you have to do it manually

2. Navigate to Preferences/Environment/Keybindings and search for "tab"

3. Click on Edit Binding at the bottom and press the tab key.

4. Press "Apply" then "Ok"

5. Key bound!

Click on the explorer or any other window that is not the editor then press Ctrl + Shift (for Mac only) + M, this is the command to "Toggle Tab Key Moves Focus" on the Keyboard Shortcuts.

To fix the issue

Pressing ctrl+M causes the ? Tab key to move focus instead of inserting a ? Tab character.
Turn it off by pressing the shortcut again.

To disable the shortcut

1. Open "Keyboard Shortcuts" with ctrl+K, then ctrl+S.
   Or go to File > Preferences > Keyboard Shortcuts.
2. Search for toggle tab key moves focus.
3. Right Click, Remove Keybinding.

Make sure this is NOT checked :

[ ] Tools | Options | Text Editor | C/C++ | Formatting | Automatic Indentation On Tab

Let me know if this helped!

In, my case I followed this advice and changed this emmet setting in vscode to false:

"emmet.triggerExpansionOnTab": false

I was receinving the error Cannot read property 'value' of null. It solved the problem immediatelly.

I am using code on xfce - did the following to fix the Tab key behavior:

File -> Preferences -> Settings

search for "keyboard.dispatch"

copy to right panel and change value from "code" to "keyCode"

Reload code

I had accidentally enabled a different mode for the tab key. Fixed it by pressing Ctrl+Shift(for Mac only)+M.

From the Visual Studio Code Keybinding docs:

| Key      | Command                                 | Command id                       |
| Ctrl + M | Toggle Use of Tab Key for Setting Focus | editor.action.toggleTabFocusMode |

The current tab control mode should also show up in the status bar:

I've had this happen before as well, where there was TeamViewer client takes the control of the TAB key. You won't know this until you close the TV window that you have open in the background.

Maybe another program is interfering? Closing Teamviewer fixed the problem for me.

[Edit] This answer is for MSVS (the IDE, as opposed to VS Code). It seems Microsoft and Google go out of their way to choose confusing names for new products. I'll leave this answer here for now, while I (continue to) look for the equivalent stackoverflow question about MSVS. Let me know in the comments if you think I should delete it. Or better, point me to the MSVS version of this question.

I installed MSVS 2017 recently. None of the suggestions I've seen fixed the problem. The solution I figured out works for MSVS 2015 and 2017. Add a comment below if you find that it works for other versions.

Under Tools -> Options -> Text Editor -> C/C++ -> Formatting -> General, try unchecking the "Automatically indent when I type a tab" box. It seems counter intuitive, but it fixed the problem for me.

Click "Tab Moves Focus" at the bottom right in the status bar.

I believe I had clicked on ctrl+M. When doing this, the "Tab Moves Focus" tab/button showed up at the bottom right. Clicking on that makes it go away and starts working again.
