Ken Bereskin points out a cool OS X feature that I didn’t know about:
There are two very strong views about how the Get Info… command should work. The first camp wants to be able to compare the info of different files at the same time, so every time you choose Get Info… a new window is displayed (just like Mac OS 9). The other camp wants the “Inspector” behavior where the info window is a single floating palette that always reflects the current selection.
What to do? Well, in Jaguar, the default is to spawn an info window for each Get Info command but hold down the Option key and the command morphs to “Show Info”, the floating palette version. The crowd cheers – everyone is happy!
