VS2010 CTRL+M keyboard shortcut has stopped working

Question

I have a strange problem which seems to have recently appeared. I used to be able to press the keyboard shortcut CTRL + M + O to \'collapse

Answer 1

The culprit for me was an AutoHotKey script that had Ctrl+M bound but not doing anything. The solution was to remove the un-used binding from the script and re-load the script. After that, everything is working.

Answer 2

Reboot worked for me.

I experienced this same issue out of nowhere (CTRL+M stopped responding).

I read the suggestions here but I could not find what process was causing it. I rebooted my laptop & the problem was solved!

Answer 3

I had the same problem. Bing Bar was installed but disabled in both FF and IE (FF had disabled it itself on security grounds, in IE I disabled it). I couldn't find any process specifically for the Bing Bar, but Ctrl + M stopped working if IE was running. Unistalled the Bing Bar and the problem went away. Thanks:)

Also, just to confirm it's not a Visual Studio issue - Ctrl + M stopped working in other programs too (at least SQL Navigator, which is quite an old program that I doubt is aware of and trying to use the Bing Bar - my guess is that it takes over Ctrl + M from everything).

Answer 4

I'm running VS2010 inside VMWare Fusion on a Mac.

For me, it stopped working after updating VMWare Fusion to version 4.1.2

I fixed it by unticking "Minimize Window (⌘ - M)" in Preferences > Keyboard & Mouse > Fusion Shortcuts.

Answer 5

Skype was the culprit for me. Turns out I enabled keyboard shortcuts for it and Ctrl + M was "Mute Microphone". Hope this helps others.

Answer 6

I have Skype installed. It had CTRL + M enabled for muting microphone.

Check all open programs and check their settings/options/preferences to see if they are using system wide shortcut keys and disable/modify accordingly.
