You can use the AutoCorrect feature to correct typos and misspelled words, as well as to insert symbols and other pieces of text. AutoCorrect is set up by default with a list of typical misspellings and symbols, but you can modify the list that AutoCorrect uses.

The AutoCorrect dialog box includes a variety of options that control automatic substitutions which are divided in two tabs: The AutoCorrect tab and the AutoFormat as You Type tab.

This tip is about changing number separators in your system that are used in Excel by default - semicolon to comma, comma to semicolon, comma to point, etc.

As well as AutoCorrect entries, you can create AutoCorrect exceptions - specific terms when you don't want AutoCorrect to replace text when it normally would.
