The Editor » Delimiters branch of Settings has the following options.
This setting determines the character following a filename that allows you to add /xxx to go to a line number or column number. If this character conflicts with a file or path name it can be changed to a character that is not likely to appear in a file or path name.
Selection of text by double clicking the primary mouse button (usually the left button) is supported by default. Normally a single word is selected made up of any alphanumeric character or underscore '_'.
If you hold the Ctrl key while double-clicking the primary mouse button, a string is selected rather than just a single word. This can be very useful in selecting filenames, email addresses, etc. The characters that delimit the string are configurable with the two options above. This works on a single line only.
The delimiters specified here – one for the left edge of the text to be selected and one for the right edge – define what characters should be used to stop any further text from being selected. If a space only is specified in each field all text either side of the caret position will be selected until a space is encountered.
