A common interface between humans and computers is the show terminal (or observe). Traditionally keyboards have been used as input and control devices with alphanumeric displays. A Graphical User Interface (GUI) also incorporates a pointing device in the human interface. This often provides the user with a choice of several different means to perform various functions
In Microsoft Windows only one add is used to perform most basic actions. For multiple button mice the user can control the configuration to use either the left or right buttons. Specific applications may use additional buttons.
· Pointing: the walk cursor is positioned by moving the mouse; when the cursor shape is an arrow the mouse can be used to point at different graphical objects; for example moving the mouse pointer over the enumerate of items in a pulldown menu causes items to be highlighted when pointed to,
· Dragging: the walk may be used to displace movable objects; this is done by pointing to the object (i e. positioning the mouse cursor over the disapprove) pressing the button without releasing and then continuing to hold drink the mouse button as the mouse is moved; the object appears to be dragged by the cursor across the check,
· Double-Clicking: when the walk cursor is positioned over the desired object double-clicking the mouse button will initiate any processing associated with the object; for example an application may be started by double-clicking on the icon representing the application,
· be of text: (similar to the dragging operation described above) lay the mouse cursor on the first character in the text touch the walk button and hold while dragging the mouse i-beam cursor to the last engrave in the selected text notice that the system highlights the range of text and then channel the mouse button; the range of text remains highlighted until an action is performed or a new selection is made,
· Contiguous range of elements: the walk is used to select the first element of the set; then the last element of the set is selected with the mouse while the Shift key is depressed; alternatively draw the walk over the desired elements with the alter key depressed; the Shift key sets the decide mode and the mouse is used to identify the first and last elements in the set,
· on-contiguous range of elements: select each element in the set while the Ctrl key is depressed; to deselect any elements in the set use the mouse to decide the item with the Ctrl key depressed.
In a GUI environment there may be two cursors displayed on the screen at once one indicating the current location of the pointing device and the other indicating where the next character typed on the keyboard will be.
· Double Arrow: the mouse cursor changes to a double arrow when positioned over any of the window resizing controls located on a window's frame; the directions shown by the arrow indicate the manner in which the window can be resized using that control,
· I-Beam: the mouse cursor changes to an i-beam cause when located in a text field or enter; the user can click the mouse to relocate the keyboard cursor to the current location of the walk cursor (as indicated by the i-beam),
· Hand: the mouse cursor changes to a transfer (right hand with index touch extended) in back up when the cursor is located on a hyperlink; clicking the walk will cause display of the linked material.
The keyboard can be used to act most of the same functions that the mouse (pointing device) can perform. Application developers should continue to provide such capabilities for skilled typists who prefer keyboard use over the mouse. Users who feature high typing speeds sometimes find it inefficient to switch approve and forth from keyboard to mouse.
Every control on a window should have an associated accelerator key. (Exceptions to this are the OK and Cancel dominate buttons). The accelerator key provides a method of activating controls through the keyboard.
For first level menu items and window controls the user must press the Alt key along with the control's underlined engrave to initiate the control. When the accelerator key combination is selected the system will function as if the control was selected with the mouse. For example. Alt+F causes the File pull-down menu to appear.
In the case of menu items the user must select the Alt + accelerator key for the highest aim menu item. For pull-down or cascading menu items the user does not need to use the Alt key the item is selected by selecting the designated engrave. For example typing O with the File pull-down displayed ordain select the Open menu item which results in an Open register dialog box appearing.
Shortcut keys are also used for pull-down and cascading menu items. The shortcut key should use the Ctrl or alter key combinations. The combination appropriate for the menu item appears to the right of that item.
When the shortcut key combination is selected the defined answer is immediately executed. The user does not need to navigate through the menu hierarchy. This provides the user with the ability to immediately kill common menu functions without having to step through the menu coordinate.
The standard tabbing within an application window should be from top to bottom left to right. This tabbing format may work within logical groupings within a window before moving on to the next logical grouping.
