To print and display from the source window:
Select the variable or expression by dragging over it with the mouse or double-clicking on it.
Right-click the mouse to display a pop-up menu.
Click on Print in this menu to display a snapshot visualizer containing the value(s) of the selected variable or expression at that point in the program's execution.
Click on Display to display a visualizer that is automatically updated whenever execution stops.
To print without bothering to display the menu, press the Shift key while selecting the variable or expression.
Prism prints the correct variable when you choose it in this way, even if the scope pointer sets a scope that contains another variable of the same name.
