I have always felt that applying a leader fill to tab stops results in a coarse look, especially in a table of contents. So instead of using the leader fill, I usually create a character style with a dotted stroke underline, which I then apply to my right indent tabs. This method gives me greater control over the stroke weight (dots), resulting in a more refined appearance.
Besides applying the dotted stroke underline to the tab, I insert a quarter space without an underline before and after the tab so that the stroke doesn’t butt up against the T of C entries and page number. I can easily set this up in my T of C style, but this creates a problem: the dotted stroke underline character style is automatically applied to both the tab and the quarter spaces—something I don’t want.
Currently I’m trying to learn GREP, but my knowledge is limited to the information available on Lynda.com (early in the course), contributing authors to this website, and expressions that I found on the Internet and have modified for my own needs. Is there a GREP style I can create and incorporate in my T of C paragraph style that will apply the underline character style to the tab—but not to the quarter spaces?
Any help you can provide is greatly appreciated.
