I occasionally realise that I need to remove one level of indentation when coding (such as moving code out of loop). The problem is I end up with a bunch of lines all indented more than I want it to be and the only way to indent it the way I want is by manually deleting all the tab spaces.
Is there a way to do this automatically? I use a variety of text editors such as Geany, N++, gedit, and Code::Blocks so I would like a multi-program solution to this.
