You click on a folder in the Dock—your Downloads folder, say—and there are two items you want to open. You click on one to open it, and the folder’s grid closes, so you have reopen it in order to click on the other. Or… do you?
Hold down the Option key while clicking an item in a docked folder’s grid and the grid stays open so you can click on another item.
When you have lots of Font Book Preview windows open for various fonts, either for a pre-install inspection or to compare various faces, it would be nice if you could use Font Book’s Close All command (by holding down Option as you open the File menu for the Close command) to close them. But Close All also closes Font Book’s main window, which, because Font Book is a one-window application, quits the program, too.
So, minimize Font Book’s main window (bring it to the front first, if necessary, with Window > Font Book). Once it’s safely in the Dock, Close All closes all the Preview windows without quitting Font Book, and then you can retrieve its main window from the Dock or with Window > Font Book.
Option-clicking on a folder in the sidebar shouldn’t, theoretically, do anything useful: an Option-double-click inside a Finder window closes the window as the new item (another folder, or an application) opens. A plain click on a folder in the sidebar displays it in the current window, so why would you want to close it? Glad you asked!
