The Clipboard applet allows
simple cut copy and paste operations.
Using the clipboard is precisely equivalent to
sending the corresponding key sequences to the current application.
The user receives an email
that talks about an upcoming concert, giving various details of dates, times,
and descriptions. By using the clipboard, the user copies the start time, end
time, and description from the email into the corresponding fields of a new
event. (not implemented: they can also copy the date in a number of common
formats.)
