26.1.3 Mouse Commands for Words and Lines

These variants of Mouse-1 select entire words or lines at a time.

Double-Mouse-1

This key sets the region around the word which you click on. If you click on a character with “symbol” syntax (such as underscore, in C mode), it sets the region around the symbol surrounding that character.

If you click on a character with open-parenthesis or close-parenthesis syntax, it sets the region around the parenthetical grouping which that character starts or ends. If you click on a character with string-delimiter syntax (such as a singlequote or doublequote in C), it sets the region around the string constant (using heuristics to figure out whether that character is the beginning or the end of it).

Double-Drag-Mouse-1

This key selects a region made up of the words you drag across.

Triple-Mouse-1

This key sets the region around the line you click on.

Triple-Drag-Mouse-1

This key selects a region made up of the lines you drag across.
