This is probably a very naive Emacs question – I’m new to it.
When I’m evaluating a lisp expression, if there’s an error the debugger automatically comes up in another window. If I have *scratch* and *info* open (the former for trying out lisp and the latter for reading about it), then the debugger opens up in the window that *info* was in. At the moment, I have to switch to that window, then change it back to *info*, before returning to *scratch*. (The same thing happens if I do C-x C-b for a list of buffers.) I’m guessing there has to be a way to just close that window without this long sequence of commands. Can anyone enlighten me?
At least here on my emacs (22.3), when the debugger pops up, its window becomes the active one. There, pressing q just quits the debugger, if that’s what you want. At that point, it also gets out of recursive editing.
