Many of the graphical elements have internal properties which can be changed. This includes the contents of a particular graph, the association of a widget and the contents of a spreadsheet cell, or the characteristics of a drawing element. These properties can be altered using the Properties... menu item in the context menu which appears when the mouse pointer is placed over the graphical element and one of the secondary mouse buttons is clicked. After the context menu appears, clicking on this menu item will open up a dialog allowing the user to alter the properties of the element. Since these properties are specific to each element, these dialogs will be discussed in each of the sections below.
