Command: Edit

Undo

Lets you undo the last action you made.

Redo

Lets you "cancel" an Undo action.

Cut

Copies the selected element (Group or Item) to the Element Clipboard and then deletes it from the menu structure.

Copy

Copies the selected element to the Element Clipboard.

If the selected element has any children (i.e. elements linked to it) the copy will also apply to them. This means that the element clipboard will contain both the element and its child elements too.

See an example:

Paste

Inserts the content of the Element Clipboard into the menu structure. 

When pasting the clipboard element, a new element is added in the menu structure along with its children.

See an example:

Since groups are always linked to items, a group will not be pasted when the selected element is also a group.

Paste Values

Lets you paste the values of the copied element to the selected element (does not create a new element in the menu structure). You can always select a subset of the copied values to paste to your target elements.

Note that you can only paste to elements that are similar to the copied element; i.e. if you copied an item you can only paste its values to other items, not to groups.
