\t*** in gedit

Today I tried to replace all "N_\phi" with "N_\theta" in a document opened in gedit, and I was surprised to see a bunch of "N heta"s. "Oops!" I thought to myself, "gedit is capable of recognized \t (tab)! What should I do?" Easy my friend (myself rather), and use "N_\\theta" in the replacement field instead.
