If you've ever wanted to use keyboard shortcuts for functions you would normally use a mouse for then look in Options > Keyboard. Here you can define your own personal scheme containing shortcuts you define. You can copy an existing scheme to base yours on.
I leveraged this to map Go To Definition on to CTRL+F which suits me fine because my favourite text editor that I use for a lot of Classic ASP work uses the same short cut to search for a highlighted word.
The list of actions you can map is extensive, but it would probably be folly to go wild and re-map everything, that said there is always one or two useful amendments that make life easier.
