In order to show all available actions, you click on a link button located right above the section containing the clipboard. The new actions are then sliding in and are appended to the list of common actions. Making them visible thus moves down both copy&paste and undo/redo. The link button stays in place and now offers to reduce the list - a click slides-out the less common actions again.

These action pairs inform the user what exactly will be done should he choose to select a particular action. If the user moves the mouse over one of the members of an action pair, it is visually emphasized and takes over most of the line to reveal more details on the action it will run - it provides an invitation on hover.

In this example, a user selects a page and moves the mouse over the "copy" action. It gets highlighted and will read "copy this page". The "paste" button is hidden as the "copy" action has taken over most of the line. If the user however moves the mouse to the right to where the "paste" action used to be, the "paste" button eventually will appear again reading "paste copied pages", assuming that the user has previously copied a set of pages. If the user moves the mouse away from the "copy" button instead and onto a different row with actions altogether, both buttons become visible again.
