The first thing I stress to anyone learning to use a computer is SAVE YOUR WORK OFTEN! You never know when the program you're using, or your entire computer, is going to crash.įor the last decade, many programs have included auto-save features that save your work every 5 to 10 minutes. That's fine as a last resort, but I still prefer to make a habit of manual saving. It comes in handy when you use programs that don't have auto-save. That's why the CTRL+S shortcut is so handy. It works in nearly every program in existence and takes only a fraction of a second to type. You don't have to take your hands off the keyboard and move the mouse cursor up to the Save icon. WHAT HAPPENS WHEN YOU HIT CTRL U MANUAL.
