I just moved a bunch of local folders into Mac Mail after porting them over from a PC using the Mail import function. In trying to clean up the local folders, I find that I can delete individual mail items in a folder, but it will not let me delete the folder no matter what I do. I'm a returning Mac user after 30 years or so, so consider me a Mac newbie. Help, please!

Never mind! the ole "control" key did the trick!!
