Digital Disk Amiga uses a custom built viewer program, to make it quick and easy for you to be able to access everything that is on the disk. The viewer can be used in two ways, either by mouse or using the keyboard. By using the mouse you can click on the panel of icons at the bottom of the screen using any mouse buttons. The alternative way, which some people might prefer, is to use 'hot' keys which imitate the mouse. Here are the 'hot' keys, starring in no particular order, well except alphabetical anyway : ~~5Key/Function (RETURN - OK, ESCAPE - CANCEL) B - Background colour, changes colour from colour to black, and vice versa. C - Contents. This option does nothing when you're on the contents page already!!! E - End, goes to the last page for the current section. G - Goto. On selecting this option you are then required to type in a page number using the keyboard. Press DELETE or BACKSPACE if you make a mistake. Press OK to except or CANCEL to return to the page you came from. H - Help. This page, so I guess you know what this option does. M - Music. Use the mouse to click on a tune then OK to load that tune (unless it is the current tune playing then nothing will happen), or CANCEL to change nothing. O - Output (Print). Click on OK to start printing the current article (or if you're looking at the Contents it will print that instead). If an error occurs you will be told about it and then you'll be returned to whence you came! Click on CANCEL to return too. P - Picture. If there is a picture for that section then it will be loaded, if not it won't!. Click on this also to get rid of a picture which is displayed, or press any other button which will do it for you!, as well as performing their function too (woooh!). Q - Quit. Yes if you've had enough for now, then you will asked if you really want to quit, press OK to quit, or CANCEL to forget that you ever even contemplated quiting. SPACE - Switches the panel to the other one, and vice-versa. Handy button if you just like using the mouse! ARROW KEYS - LEFT and RIGHT move back/forward a page, and UP and DOWN move back/forward a section (Contents is section 0). Thats the lot, so a good place to end!
