The Windows->Text Clipboard menu item opens the FlexEdit text clipboard in view mode.
The text clipboard content cannot be edited. The content, or a block of the content, may be saved to a file. The clipboard content is updated when it has changed. The clipboard window may be left open but if FlexEdit is then opened, the clipboard will close when FlexEdit is closed, assuming the internal FlexEdit is opened.
