Is there a way to reveal an item in the Finder from Launchpad? Sometimes I will see something that does not really belong in Launchpad—a readme, for instance—and I'd like to see it to move it. Sure, I can close Launchpad, open the Applications folder, and hunt for it there (perhaps in subfolders), but it seems to me that there ought to be an easier way. Is there? I can't seem to find one. Right-clicking, sadly, seems to do nothing.

I'm not trying to delete items that are in Launchpad from my drive; I just want to see them in the Finder, so that I can move them around or perform other operations on them..
The answer to the question is No, there's no way to reveal an item in the Finder from Launchpad.
However, there is a relatively easy way to remove items from the Launchpad, which is what I really wanted to do, and it does not require moving the item out of the Applications folder: Launchpad Manager. It's an inexpensive utility that helps you manage your Launchpad, and, crucially, remove any items you'd like from it.
