The design of this mechanism has several implications:
??? The pasting speed is limited by network performance (practically speaking, this
has an impact only for very large amounts of data or slow network connections).
??? You can??™t paste from the clipboard after the program that placed data on the
clipboard exits (for example, if you use the Copy function in Mozilla, and then
exit Mozilla, you won??™t be able to paste into another application. The data will
be lost.)
??? Data that is placed on the clipboard but not pasted is never transferred over the
network.
??? Data is pasted in the best format that both programs can handle.
??? Only one item may be on the clipboard at a time.
A clipboard manager is a client that accumulates clipboard selections. This serves
two purposes: it lets the user preview and select from several selections, and it keeps
the clipboard data around after the source client??”the program that placed the data
on the clipboard??”terminates.
Both of these features are valuable, but unfortunately, using a clipboard manager
also has two disadvantages: all data placed on the clipboard is copied over the network,
regardless of whether it is ever used, and data stored by the clipboard manager
is converted into a single format (usually the lower common denominator??”the
most basic format for a particular type of data).
