({{, (RefLink[DelimiterFlashTime, paclet:ref/DelimiterFlashTime])
is an option for cells and notebooks that specifies how long in seconds a delimiter should flash when its matching delimiter is entered. }})

OpenersNotesSection(Spacer1)Details

(RefLink[DelimiterFlashTime, paclet:ref/DelimiterFlashTime])->0 makes delimiters not flash.

A typical default setting is (RefLink[DelimiterFlashTime, paclet:ref/DelimiterFlashTime])->0.3, which makes matching delimiters flash for 0.3 seconds.

Delimiters include parentheses, brackets and braces, [[ and ]], (* and *), and paired special characters such as ⟨ and ⟩.

If you enter an unpaired closing delimiter, the standard Wolfram System 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 (RefLink[DelimiterFlashTime, paclet:ref/DelimiterFlashTime]) at the level of a single cell, a notebook, or the whole front end.
