Avoid Repetitive Keystrokes

Using AutoCorrect as AutoReplace
There are generally words, sentences, and phrases you repeat many times. Auto-correct can really help here. For example, if you have the word "Microsoft" appearing several times in a document, simply bring up the Autocorrect option and assign a keyword/shortcut that would quickly replace itself with the whole word. So with Autocorrected it with the shortcut "ms"; every time typed in "ms" and hit the spacebar (it's important that you hit the spacebar after entering the shortcut), the "Microsoft" would magically appear.Try it out yourself

1. In Word (2003), go to Tools AutoCorrect Options.
2. In the Replace column, type in ms.

3. In the With column, type in Microsoft. Click Add.
The above is applicable to plain text. However, if you want formatted text with bolding or italics, here's how you do it.

1. Type in the formatted text first in Word, then select it and open AutoCorrect options as above.
2. Select the Formatted Text radio button on the right. The text will automatically appear in the With box. Just enter the Replace details.
Don't like the shortcut? Do this:
1. In the Replace column, type in the shortcut, ms in this case.

2. Hit Delete. Note that this change is undoable. OR If you just want to replace it (even with formatted text), use the same shortcut, but just alter the shortcut in the Replace column. Hit the Replace button to accept the change.
