Right-Click Context Menu
You can right-click an element in the North-pane or South-pane (depending on support) and open the item's context menu.
Examples of this include the North-pane Server tab where the right-click menu replicates the options available in the Server drop-down menu, and the South-pane Checks tab, where the right-click menu is the same as the Checks drop-down.
