When you’re told to “point the mouse,” you move the mouse on the desktop, which moves the mouse pointer on the screen to point at something interesting (or not).
Use the mouse to expand and contract the left panel
Click (or Left-click)
A click is a press of the mouse button — one press and release of the main button, the one on the left. This action makes a clicking sound, which is where this maneuver gets its name.
This one works just like the single click, although you click twice in the same spot — usually, rather rapidly.
Shift-click means holding down the Shift key on the keyboard while clicking the mouse. In Social Tables, use shift + click to highlight multiple objects at once to edit
This action is the same as a click, although the right mouse button is used. In Social Tables, use right-click to access additional edit options for each object
Drag & Drop (also known as Click + Drag)
The drag operation is done to graphically pick up something on the screen and move it. To do that, you point the mouse at the thing you want to drag, press and hold the mouse’s button (which “picks up” the object), and then move the mouse to another location. When you move the mouse (and keep the button down), the object moves. To release, or drop, the object, release the mouse button.
