Paste takes the object(s) in the Clipboard and puts them into
the selected window or character slot.
Clear
Clear deletes the selected object(s) without doing anything
to the Clipboard.
Copy Widths
Copy Widths will copy the character width of a selected
character to the Clipboard.
Copy Reference
Copy Reference copies a reference of a selected character
into the Clipboard, which can then be pasted to allow
layered objects. You must use Copy Reference instead of
Copy if you want to create a composite character.
Unlink Reference
Unlink Reference relaces a referenced character with
explicit paths.
Select All
Select All selects everything in the currently active window
and layer. From the Font Window you can choose Select All
to select all the character slots that are filled; Option-Select
All (Alt-Select All) selects all slots, even if there are no
paths in them.
Duplicate
Duplicate makes a copy of the selected object(s) and leaves
it on the screen slightly displaced from the original(s).
Power duplicating occurs when you duplicate the same
object several times (in the Outline Window).
