Is there a way to specify a minimum distance for a right indent tab? IE in an index I have text that is getting too close to the page numbers before it breaks to a new line.
I just encountered the same problem, and I created a new GREP style for my paragraphs that use right indent tabs.
The GREP looks like this: .(?=~y)
[i.e., select the last letter before a width tab]
To that GREP I assigned a character style that sets the kerning at 120. That seems to accomplish what I wanted when I came across this thread looking for an answer.
