DelimiterFlashTime

DelimiterFlashTime
is an option for cells and notebooks which specifies how long in seconds a delimiter should flash when its matching delimiter is entered.
  • A typical default setting is DelimiterFlashTime->0.3, which makes matching delimiters flash for 0.3 seconds.
  • Delimiters include parentheses, brackets and braces, as well as [[, ]] and (* and *), and paired special characters such as LeftAngleBracket, RightAngleBracket.
  • If you enter an unpaired closing delimiter the standard Mathematica front end will beep.
  • You can use the front end menu item Check Balance to select ranges with balanced delimiters in an expression.
  • You can set DelimiterFlashTime at the level of a single cell, a notebook, or the whole front end.
