Adding Times and Dates to Aperture Album Names
It is common to differentiate albums in a project by adding the dates to the album names.
If you add dates to an album name, avoid using special characters like the slash (/), since
that may be interpreted by Mac OS X as a file separator.
Quickly Accessing Commands
You can access commands via a shortcut menu, as an alternative to using the menu bar
at the top of the screen or pop-up menus within a window.
To view the shortcut menu:
m Position the pointer over the Projects panel, then Control-click.
Note: Although accessing commands from shortcut menus can help you work more
quickly, keep in mind that not all commands are available in shortcut menus.
