Using AutoCorrect to add symbols. And another little tip...

By activating the AutoCorrect option in Office, you can add special symbols by writing special text.

Try it yourself - turn the cursor to English, and try:

(C)
(R)
(TM)
– – >
< – –

And one more nice shortcut:

To increase and decrease the font size, just highlight the desired word or words, and click on:

< + Ctrl + Shift to enlarge the text.
> + Ctrl + Shift to make the text smaller.
