Visual Studio Shortcuts: Disabled?

Question

This has finally driven me completely mad. Most of the Visual Studio specific keyboard shortcuts (meaning shortcuts like ctrl+c or ctrl+v are not included in this list) for both VS2010 and VS2013 haven't been working for me for the last two months, and I have no clue how/if I managed to disable them.

Examples of shortcuts that aren't working (by no means an inclusive list)

Note that for all of the below I have confirmed that the expected shortcut combination is assigned to the action I'm trying to perform.

• F12 to go to definition
• All debugging shortcuts
• F5 to start debugging

What I've Tried So Far

• Tools → Options → Environment → Keyboard → Reset
• Tools → Import and Export Settings → Reset all settings (which seems to be the exact same thing as the first bullet point, but I'm desperate here)
• Visual Studio restarts (multiple)
• Deleting .suo file
• Computer restarts (multiple)

Any suggestions for what else I can try to get these shortcuts to work again?

It turns out this wasn't a Visual Studio issue at all. Apparently on my new keyboard there is a 'F Lock' key that locks all the function buttons...and I must have accidentally pressed it at one point. It just so happens that Visual Studio is the only program that I currently use that has so many function key hotkeys.
