New Line in mulitine edit controls

[sigh71]

I have a macro, which is basically a list of files, 1 file per line...

at the moment to add a new file i cut and paste the text into a text editor so i can add new lines to the macro, because if i press enter in the macro dialog, it presses the ok button.

is there a way of entering a new line in the edit controls?
i notice in windows messenger you can go to a new line by pressing shit+enter, this would be a handy feature in visual build.
