For practical work the student has to use:

·        Menu commands;

·        Buttons from the toolbar of the program Capture toolbar and from the  tool palette;

·        pop-up menu commands showing up when right-clicking .

 

The menu commands are active depending on the actions we take  and on the selected  components.Similarly the pop-up menu has a different content depending on the context.

 

The two toolbars are dockable that is we can move them in different positions being reconfigurable as shape.When placing the pointer on buttons a legend with its name is displayed (tool tips). The bars’ initial postions were presented in figure 3 and the significance of the right bar instruments  are presented in figure 4.
