Another symptom, when trying to use this key combination it immediately marks the entire file as edited without actually (visibly?) adding anything. CTRL-Z resets the file back to normal.

Hi Dennis,

This looks interesting. We will check this issue. At the moment it looks like it's something in Visual Studio shell itself, but anyway we'll check if it's true and if we can do anything right now to correct such behavior.

I'll let you know once we have any updates.

Thanks,

Vladimir

It's the shortkey for auto formatting. Just remove the ctrl+alt+^ entry and use ctrl+Q for formatting. That's how I do it on Azerty. :)

Ah, you're right, that was the issue. I suspected something like that, but didn't find the shortcut in the definitions. I completely missed that there were secondary shortcuts for some things as well.

In the event someone else has this problem: 

Go to Tools > Options > Keyboard

Search for 'Edit.FormatCode'

In the dropdown for shortcuts the default for me was Ctrl-Q, but the one that Vincentius mentioned is in the list as well. Select it and click remove.
