Abstract:

The keyboard is rarely the friendliest path to symbols and special characters. Sometimes a bit of menu magic can guide you past the overwhelming Glyph palette. Indeed, the Special Character flyout palette in Adobe InDesign CS3 is a great shortcut to frequently-used characters and will spare your fingers the keyboard contortions.
