Common keyboard commands
If you do not know how to copy/paste without a mouse, you are not computer literate. Sorry! Every operating system has some universal keyboard commands, and while knowing them won't add 30 minutes back into your day, it will take a lot of the "friction" out of using a computer. Learning these commands is more a matter of routine than anything else; a short tutorial done once a day for a week will probably be enough to put you in the habit, and it will make you a happier user.
