The Graph Editor had no menu for keyframes. Right-click now opens the same key menu as the
Timeline, for the commands that apply from the graph: Edit Value, Copy and Paste, selecting
equal or neighbouring keys, Hold, Rove Across Time (spatial properties only), Easy Ease,
interpolation and Delete. The items run the existing keys.* commands, so undo and the
automation ids are unchanged.
A right-click on an unselected key selects it first, as a click does.
Not covered by an automated test; checked by compiling and by reading the menu against the
Timeline's.
