Touchpad Usage
Clicking/Tapping - With the pointer over an item, press the left
button or use your fingertip to touch the touchpad lightly, keeping
your finger on the touchpad until the item is selected. The selected
item will change color.
Double-clicking/Double-tapping - This is a common skill for
launching a program directly from the corresponding icon you
select. Move the pointer over the icon you wish to execute, press the
left button or tap the pad twice in rapid succession, and the system
launches the corresponding program. If the interval between the
clicks or taps is too long, the operation will not be executed.
Dragging - Dragging means to pick up an item and place it
anywhere on the screen you wish. You can move the pointer over
the item you select, and while keeping the left button depressed,
moving the pointer to the desired location, then release the button.
Or, you can simply double-tap on the item and hold while dragging
the item with your fingertip.
