In my Indesign Style (CS6 on Windows 7) I want to apply the style underline to all initials that come after a tab.

NASCAR    National Association for Stock Car Racing

So the initials all get underlined in the expansion to indicate the letters for the acronym. I am making a list of acronyms, so I want to grep this.

Here is what I have:


These will only underline the first letter after the tab.

So I thought of just underlining capital letters in the expansion, because in acronyms it's not always just the first letters of words:


But that does the same thing.

How can I do this?


Solution 1

You can achieve this with 2 Grep styles (in the right order).

First catch all uppercase characters and apply underline character style to this first query:


Then catch all characters before tab and apply a new character style set with no underlining:



Solution 2

For an 'all-in-one' solution, try this:

Which basically would translate as Catch all uppercase characters except those followed by the pattern 'Any character (zero or more times) followed by a tab'

  • Solution 2! This is absolutely perfect. I don't even have to manually underline anything of the characters. I had actually derived the idea already of using capitals to cause the underlines, but I couldn't figure out how to get them on all the ones after the tab and got pretty close with this: (\u+(?=\l)). But yours is perfect! – bgmCoder Nov 10 '17 at 16:18

It’s all depends of your actual text... If you just have a bunch of lines with Acronymes you can use this simple one.

  • Thanks for your help. However, this also underlines letters in the acronym itself - nothing before the tab should get underlined. – bgmCoder Nov 8 '17 at 14:23
  • How do use this without affecting what comes before the tab? – bgmCoder Nov 8 '17 at 16:22
