- Commands: Screen control
- ========================
-
- While hypertext effectiveness centers mostly on browsing
- interfaces, the important page control commands are:
-
- ┌──────────────────────────────────────────────────────────────┐
- │ PgDn Displays next screen │
- │ PgUp Displays previous screen │
- │ Home Displays first screen of file │
- │ End Displays last screen of file │
- └──────────────────────────────────────────────────────────────┘
-
- The bottom of the screen displays the status line <link41>
- showing the current screen number, total number of screens, and
- "dashboard lights" recommending keys to press with longer files.
-
- While the size of the displayed file is limited only by available
- memory, most hypertext files are best understood if keep slightly less
- than one screen in size because:
-
- (1) smaller screens load faster ............. <link36>
- (2) users read only first screen
