The user clicks on a point within an image and the corresponding x- and y-coordinates are sent to the program. Image maps are used when creating Web pages containing maps with instructions to click in a certain area in order to view a detailed map of the region. The example embodiments cuentos-infantiles.net described herein can be used with computer hardware and software that perform the methods and processing functions described previously. The systems, methods, and procedures described herein can be embodied in a programmable computer, computer-executable software, or digital circuitry.
If a different sound is made in response to key clicks in the menu then this may help prompt the user. You would not want a different sound for each menu item, but the sound at a leaf could be different that the sound on reaching elcredocatolico.com a node.

Replace toolbars and menus, organized commonly used commands into sets of related activities. These activities are displayed as tabs and appear in the first ribbon. Computer-based training and on-line help services provide an integrated training environment on user workstations. Training is available on an as-needed basis for any application available in the environment. Electronic messages are provided at the stroke of a key from anywhere within the application. This includes tutorial training on the application in use and the availability of off-line, on-site interactive training.

- These aspects can be emphasized by using the alternative term and acronym for windows, icons, menus, pointing device .
- The concept of icons was later introduced by David Canfield Smith, who had written a thesis on the subject under the guidance of Kay.
- The graphical user interface is presented on the computer screen.
- It is the result of processed user input and usually the main interface for human-machine interaction.
