Quark & Right-Indent Tab

I think this is a special character but not entirly sure. I have a large index in which I woiuld like to change a single tab to the Alt-tab. Also can I change the font of type between specific characters. For example:
Product Name 1 (tab) 120 (return)
Product Name 2 (tab) 145 & 146 (return)
Product Name 3 (tab) 263 & 264 (return)
What I would like to do is change the font of all characters between the tab and returns. Would this be best done with a repeat through lines of paragraph etc not sure of the best route to take with handling text in quark.
