To delete an object from the clipboard, click first on the appropriate position in the clipboard and then on the trashcan icon.
If you have selected an object both in the clipboard and in the document you will get the following alert:
In this you can decide which of the two objects – if any – should be deleted.
As, due to the context sensitivity of the Clipboard module, this deletion function is available more or less in every module, we recommend that you place it on a keyboard macro so that the same key presses can call up this deletion function anywhere.
Tip: Why delete immediately? In most cases it will be enough (and steadies the nerves) to place objects and frames no longer needed in the clipboard.
