Syntax: AutoMatchBracket [0..15]
Abbreviation: AMB
sets the auto match bracket mode. When the cursor is on a
recognized bracket (‘{}’, ‘()’, ‘[]’, ‘<>’, or ‘`'’) and
the associated matching bracket is on the screen, that matching bracket
will be indicated according to the mode. The mode is either zero for no
bracket matching, or the sum of 1 (altered foreground and background
brightness), 2 (inverse), 4 (bold), and 8 (underline). If no mode is specified,
ne prompts you for one. The default mode is 1. See MatchBracket.
