Shortcut keys help provide an easier and usually quicker method of navigating and using computer software programs. This is a list of some of the most common Microsoft Office keyboard shortcuts:

1. 1. Ctrl+Z is the wonderful undo combo. It basically undoes your last action. Programs vary in the number of times you can undo something, but some will let you Ctrl+Z all the way back to the beginning. And, of course, there is a redo command, just use Ctrl+Y.
2. 2. Ctrl+B, Ctrl+I, or Ctrl+U apply bold, italics, or underline to highlighted text, respectively.
3. 3. Ctrl+P prints what you have open in an active window.
4. 4. Ctrl+Backspace erases an entire word at a time, instead of a letter. Ctrl+up or down arrows let you scroll an entire paragraph at a time, instead of one line, and Ctrl+Shift+up or down arrow will select an entire paragraph.
5. 5. Ctrl+Enter inserts a page break in Word.
6. 6. Alt+Ctrl+C inserts the copyright symbol ©, Alt+Ctrl+R inserts the registered trademark symbol ®, and Alt+Ctrl+T makes the trademark symbol ™.
