The clipboard Command

The clipboard command manipulates values in the CLIPBOARD selection. The CLIPBOARD is meant for values that have been recently or temporarily deleted. It is use for the copy and paste model of selections. Prior to Tk 8.4, you had to use the selection command to retrieve values from the CLIPBOARD selection:

selection get -selection CLIPBOARD

However, Tk 8.4 introduced a clipboard get operation as a convenience for retrieving the clipboard value.

Table 38-2 summarizes the clipboard command:
