My VS2013 shortcuts were working fine and I also use some addons for my productivity. But lately I observed my most of the default VS shortcuts weren't working anymore (e.g. Ctrl K, Ctrl C for commenting, Ctrl K Ctrl T for viewing hierarchy).
I tried resetting the keyboard shortcuts to DEFAULT but that didn't work as well. (Using the foll. steps)
Menu: Tools -> Options -> Environment -> Keyboard -> RESET Button -> Confirm Yes.
I'm unsure why the shortcuts aren't still working.
The list of the installed addons (that may be fudging up the shortcuts, I tried combinations to disable them and try again but in vain)
Can anybody please help?
