Showing Balanced Delimiters

When you position the cursor inside a pair of delimiters, that is, inside ( ), [ ], or { }, and select Balance Delimiters from the Text menu, the string inside the pair of delimiters is highlighted. If there is not a pair of delimiters, instead MATLAB beeps. In this example, when the cursor is positioned before /norm, as indicated here

selecting Balance Delimiters highlights the selection as shown here.

For other appearance aids related to balancing delimiters, see Syntax Highlighting.
