Using AutoCorrect to type Infinity symbol

Another way to obtain the Infinity symbol is through the use of the AutoCorrect feature.

It is a facility designed for correcting spelling mistakes like adn to and.

Using this feature, you can assign a code to the Infinity symbol (such as INFSYM).

This way, whenever you type the text INFSYM, Word will think that you actually wanted to type and will convert it into the Infinity symbol automatically.

What makes this approach interesting is that you can assign any code you want to the symbol and Word will be more than glad to give it to you whenever you type the code.

Without further ado, here are the steps to use the AutoCorrect technique to insert Infinity symbol on Word.

  • Go to InsertSymbolsSymbolMore Symbols to display the Symbol dialog box.
  • Click to select the Infinity symbol from the library of symbols.
  • Click on the AutoCorrect… button to display the AutoCorrect dialog.

  • In the Replace: box, type INFSYM (or any AutoCorrect text you want to assign to the Infinity symbol)
  • In the With: box, make sure it contains the Infinity symbol. You can press 221E followed by Alt+X to insert the symbol or copy and paste from a document or a webpage.

  • Click Add, then click OK.

Word will automatically insert the Infinity symbol into your document whenever you type INFSYM.

Below are some few things to note though when you are using the AutoCorrect Method to insert the Infinity sign.

  • AutoCorrect is case sensitive. Meaning if you type infsym (in lowercase), Word will not convert it into the Infinity symbol unless you type INFSYM (in uppercase).
  • If there is any text before INFSYM, Word will consider the code as part of the text and hence will not convert it to the Infinity symbol. For example, XINFSYM will not get converted, but X INFSYM    will get converted to X ∞.
