I have found Komodo IDE excellent for stepping through PHP code (instead of old-school print statements for debugging). But is it possible to debug a userscript in a similar manner? When the file I’m currently editing is the userscript itself, and I go to the Debug menu, the options for starting debugging are grayed out. When I right-click on the userscript name in the right pane, there isn’t an option for starting debugging. (And that second approach would be needed in those cases where the userscript is supposed to operate on a file other than itself, such as a text file, in which case that other file would be the one in my current window, and thus the Debug menu wouldn’t be applicable.)
