NCSA Mosaic for MS Windows User Guide: Tips and Tricks

Features for Disabled Access

The options below are included in NCSA Mosaic to help improve Internet access to the disabled. Some options are specific designed for disabled access; others are standard options.

You configures these preferences in the various Preferences... menus (select Preferences... from the Options menu or press Alt+ENTER). See Chapter 4, "Customizing," for detailed information on changing preferences.

NOTE: For more information on the right mouse menu, see "Features for Disabled Access" on page 6-6.

Adjusting Font Size with Magnification

The plus and minus keys (+, -) on your keyboard are directly linked to a magnification feature that proportionally adjusts the size of all fonts to a maximum of five times their original size. Press the plus (+) key to increase the size of the current font settings. Press the minus key (-) to decrease the current font settings.

Font Size

You can change fonts in two ways:

For example, suppose you want to change the size of the Normal font. The easiest way is to right mouse click on some normal text and select Change Normal Font from the right mouse menu. Mosaic opens the Font menu where you set the size and color of the font. When you click OK, Mosaic changes the font and saves your preference setting.

See "Adjusting Font Size with Magnification" on page 6-6 for another way to change the on-screen fonts.

Background Color

The background color can be changed from the General menu (select Preferences... on the Options menu). Click on Background Color to open the color palette window. Select the desired color and click OK. Your new color is saved as your preference.

Anchor Highlighting

NCSA Mosaic has three choices for highlighting anchors: framed, button, or hatched. Select the one you prefer using from the Anchors menu (select Preferences... on the Options menu). For more information see "Current Anchor Highlighting" on page 4-3.

You can also change the color of the highlighting. Click on the Change button, which opens the standard color window. See "Current Anchor Highlighting" on page 4-3 for additional information.

Anchor Color

Mosaic lets you mark the three anchor types (unvisited, visited, and cached) for easy recognition. Unvisited anchors represent the documents you haven't visited (viewed) and by default are colored blue. Visited anchors represent documents that you have already visited and are colored red. Cached anchors are visited anchors with a copy of the document residing locally in your disk cache. By default, cached anchors are green.

Changing the color of the fonts is done in the Anchors menu (select Preferences... on the Options menu). See "Fonts" on page 4-11 for detailed information.

Audio

In the audio preferences menu, you can associate .wav audio files with up to twenty-five common Mosaic commands. See "Audio" on page 4-4 for detailed information.

Context Sensitive Menus

The right mouse button contains context sensitive menus. See "Features for Disabled Access" on page 6-6.

Pen Movement

Mosaic recognizes pen movements. When the middle mouse button is clicked, Mosaic is sensitive to mouse movements as input commands:

page up
move mouse up
page down
move mouse down
move forward in history
move mouse right
move back in history
move mouse left
go to the defined home page
move mouse in L shape
open the Preferences... menu
move mouse in backward C shape
To activate this feature, include the command line switch -pen to your Mosaic icon properties (see
"-pen" on page 5-16). The next time you open Mosaic it will be movement sensitive when you depress the middle mouse button.
