Speaking of blue halos…
Does anyone have any idea what the blue halo in the following picture (taken from Mac OS X’s Installer application) means?
We already have the blue tint used for default buttons in Aqua windows:
This blue tint is used to indicate that this is the default button and that it can also be pressed by hitting the Return or Enter key on the keyboard.
And then we have the regular Aqua button, which is the same without a blue tint (see the “Cancel” button in the picture above) and usually requires a mouse click, unless it has a special keyboard shortcut (“Cancel” can usually be pressed by hitting the Escape key).
But what on earth is a button with a blue halo? What does it indicate? It’s not the default button, because hitting the Return or Enter key doesn’t do anything. You still need to click on it.
I’ve checked Apple’s Human Interface Guidelines for controls and I see no mention of this type of button.
Then again, the buttons used in the guidelines to illustrate the text are still pre-Jaguar buttons, so that tells you how up-to-date the documentation is!
