The right mouse button has three uses in SAP2000:
Right click in the menu/toolbar area to customize the menus and toolbars. See Customize Toolbars for more information.
Right click on an object in a display window to open a form with information about that object. The type of information shown depends on what is being displayed in the window.
Right click in the background (not on an object) of a display window to access a menu of selected commands that includes the following:
Lock OnScreen Grid System Edit - This is a toggle that locks or unlocks on-screen editing of the grid system.
Delete - Left click on an object to select it, then right click anywhere in the active display window and select the Delete option to delete the selected object.
Edit Dimension Preferences - This command accesses the form used to set the dimension and tolerance preferences.
For all other mouse functions in SAP2000, use the left mouse button.
