Microsoft Visual Studio offers a lot of flexibility in creating keyboard shortcuts. To create, edit, or view existing Visual Studio keyboard shortcuts, you need to go to the Tools -> Options dialog and choose Environment -> Keyboard. To create new commands, you can type in the command you want to create a shortcut for in the "Show commands containing" box or you can select the command from the list box (which I always find easier). Once you find the command for which you want a shortcut, go to the "Press shortcut keys" and press the keys you want to use a shortcut. Do not try to type text for the keys, press the keys themselves. For example, don't type in "Ctrl" for the Control key, just press the Control key and it will fill in the Ctrl text for you.

If you want to see what commands are currently assigned to a key combination in Visual Studio, don't select a command first, just go straight to the "Press shortcut keys" and press the combination you are interested in. Below this, in the "Shortcut currently used by" box it will list the command or commands that currently make use of this keyboard sequence.
