Noe that different software packages have different keyboard combination shortcuts. You can find some windows xp shortcut keys
here or use
google.
But why do you want to make life difficult for yourself? In as much as knowing some of the common key combination is good(in a situation you mouse decide to go crazy on you), the mouse is there to help simplify your everyday work. USE IT. In this day and age, i don't think you will impress anyone by knowing all the keyboard shortcuts there is to know.
Good luck.
