Mouse actions
A mouse allows you to (1)............................. the cursor and
move around the screen very guickly. Making the same movements with the arrow keys on the keyboard would
take much longer. As you (2)___________ the mouse
on your desk, the pointer on the screen moves in the same direction. The pointer usually looks like an l-bar, an arrow, or a pointing hand, depending on what you are doing.
A mouse has one or more buttons to communicate with the computer. For example, if you want to place the insertion point or choose a menu option, you just
(3)..................... (press and release) on the mouse
button, and the option is chosen.
The mouse is also used to (4)__________ text and
items on the screen. You can highlight text to be deleted, copied or edited in some way.
The mouse is widely used in graphics and design. When you want to move an image, you position the pointer on the object you want to move, press the mouse button,
and (5)____________ the image to a new location on
the screen. Similarly, the mouse is used to change the shape of a graphic object. For example, if you want to
convert a sguare into a rectangle, you (6)__________
one corner of the sguare and stretch it into a rectangle.
The mouse is also used to start a program or open a document: you put the pointer on the file name and
(7)____________ on the name - that is, you rapidly press
and release the mouse button twice.
