EditorGUIUtility.systemCopyBuffer

설명

The system copy buffer.

Use this to make Copy and Paste work for your own application. The systemCopyBuffer captures any text that is selected on the machine. This does not specifically have to be text that is selected in Unity. Reading and writing systemCopyBuffer is possible.
Have more than 1 saved "copy" command.

// Example that shows up to 5 strings.  These strings are captured from Copy
// commands on the machine.  The Current buffer at the bottom of the window shows whatever string
// is copied.  The string can be copied to one of the five Save rows when the Load toggle is
// five Save rows when the Load toggle is off and one of the horizontal buttons is pressed.
