Client Menu Reference : The Edit Menu : Undo
   
Undo
Allows you to undo some of the errors you may have made while entering text into fields. It reverts to the former text entry. It works for string fields of the Information window or view, for the Quicksearch entry field and when renaming categories. (Disabled if not available.)
Note that this function is limited to revert text entries, it will not reverse any functions.
Cut
Removes the current item or text selection and places it on the Clipboard so that it can be pasted elsewhere.
Copy
Copies the current item or text selection to the Clipboard so that it can be pasted elsewhere. When copying records or categories, a temporary metadata template is created additionally that can be used to transfer selected metadata to other items.
Paste
Places the contents of the Clipboard into the current location or text insertion point. Pasting a copied record into a catalog duplicates the record, but with a different creation date. Pasting a copied category into a category tree creates a new category with the same name below the selected target category. (This works only if “Keep category names unique” is not activated in the Catalog Settings.)
