Right Mouse Button
When you click the mouse button on the right in a FluidSIM window, the appropriate context menu is opened. If the mouse cursor is located above a component or component connection, the item will become selected. If this component was not yet selected, then a possibly existing selection of other components will be de-selected.
Clicking the right mouse button on a component (connection) is actually a short cut for the following two actions: Clicking the left mouse button on the component (connection) and opening a menu.
