There are contextual menus all over the IDE that you can open by right-clicking. This saves you from having to look for the appropriate command in the main menus. Here are some examples:

Right-click a node in the Explorer to get a list of all commands available for that object.

Right-click an empty area in the main window's toolbar panel to set the toolbar configuration.

Right-click a workspace tab (such as Editing or GUI Editing) in the main window and choose Customize Workspaces to configure that workspace.

Right-click the Watches node in the Debugger Window to add a watch.
