Unformatted text preview: e. Note that notifying the system of a
particular choice out of the various options provided by the software is much easier with
a mouse than pressing various key combinations. With the proper software, a mouse can
also be used to draw pictures on the screen and edit text.
The following five simple techniques are used to carry out the various types of operations
possible with a mouse:
1. Point. To point means to move the mouse suitably to move the graphics cursor on top
of an icon or a menu item.
2. Click. To click means to press and release the left mouse button once. It allows
selection of the menu item represented by the icon, which is currently being pointed to by
the graphics cursor. The function of the right button varies between software packages,
but often it is used to call up a menu of options.
3. Double-click. To double-click means to press and release the left mouse button
twice in rapid succession. It allows execution of the program represented by the icon,
which is currently being pointed to by the graphics cursor. The function of doubleclicking the right mouse button varies between software packages.
4. Simultaneous-click. To simultaneous-click means to press and release both the left
and right mouse buttons simultaneously. It is used by some software packages to give
added functionality to the mouse. The actual functionality for simultaneous-click varies
from one software package to another.
Drag. To drag an item means to position the graphics cursor over the item, then
depress the button and hold it down as the graphics cursor is moved on the screen by
moving the mouse. You may drag an icon to change its location on the screen. When
using a graphics software program, you drag the graphics cursor to draw graphics objects
(such as lines, circles, curves, freehand drawings, etc.) on the screen. When using a
word processing program, you select a block of text for deleting it or for changing its
style by dragging the graphics cursor from the beginning to the end of the block.
