I almost never, ever use a mouse (MacBook Pro's trackpad is the best pointing device I've ever encountered), but when I do, I usually select thing with ONE click of the mouse, instead of two (I'm lazy). For example, if I want to select 'Print...' under 'File' menu, I I move the cursor to the 'File' menu, hold left (or right, if I want to use something off a contextual menu) mouse button down, move the cursor down and over 'Print...' and let go of it. It's much faster I think, and I'm used to it. It's useful specially when you have to right click on something and then select an item with the left button.
The old, naïve `select`s all behave as expected (as they're usually native UI elements), but this `select2 ` thing does not work like this.
