## Bracket Matching

A handy feature of the Understand editor is syntax bracket matching. Use this feature to find the matching ending bracket of syntactically used braces, parenthesis and brackets. Symbols matched are (,),{,},[,]. Matching isn’t done inside comments.

There are two modes. The first is the use of the keystroke CTRL-M to “match” a brace, parenthesis, or bracket that the cursor is over. CTRL-M isn’t active unless over a symbol that it can match. CTRL-M then jumps the editor to the matching end or beginning brace. Another CTRL-M takes you back where you started. Try it - most programmers who try it come to depend on it.

Another variant of bracket matching is that when enabled each time you type one of the bracketing symbols the editor will quickly highlight the entire region being bracketed. This too is handy for quickly and efficiently entering syntactically correct code that does what you hope it does.
