Description : I have a text file, and i want to replace P(blah) with P[blah], everywhere that it exists?
Last Answer : Hmm I can't think of any special programs at the moment, You could however do a control - F (or command - F) keyboard shortcut and bring up the find box. In another tab there should be an option ... all). I'm not sure how that would handle different parenthesis'. I'd make a backup, just in case.
