Sometimes, I can’t help playing the “what-happens-if-I-do-this” game on my Mac, and more often than not, there are neat little features to be found that are scarcely documented, if at all. Here a two finds of this kind:
You will already know that command-dragging the title bar of a window that’s in the background lets you move that window without making it active, i.e., without bringing it to the front. However, this also works for re-sizing: by command-dragging the window’s bottom-right corner, you can resize the window while it stays in the background. Very useful alternative to moving the whole window if you need to get a quick view of what’s behind it.
Another well-known feature of OS X’s UI is that you will see the folder hierarchy that leads to a Finder window’s contents when you command-click the title of the window. This works similarly in most document-based applications like TextEdit, Preview, etc., but some apps use this feature in unusual ways: command-click on the title of a Safari window, and you will see the URL’s hierarchy, instead.
Do you know any applications that do unusual things when command-clicking on their windows’ titles?
