The aim of Enhanced Clipboard is to allow you to append multiple entries to a private clipboard.
The Enhanced Clipboard Menu
With the 'Copy' option you can add the currently selected text to the private clipboard. 'Copy Procedure' allows you to copy the current procedure. Next is the option to 'Clear' the clipboard and then finally to 'Paste' the contents to the current location in code.
In General Options you can set two options that control Enhanced Clipboards behaviour. 'Clear Clipboard on Paste' will clear the contents on a paste while 'Add Blank Line on Copy' will simply insert a blank line between the new item and the existing contents on any copy command.
