Formal metadata information and software
| Key | Unmodified Key | Control-Key | Alt-Key |
|---|---|---|---|
| Up | Prev line | Prev paragraph | Prev element |
| Down | Next line | Next paragraph | Next element |
| Home | Start of line | Start of value | Root element |
| End | End of line | End of value | Last element |
| PgUp | Previous window-full of text | Make left edge of text visible | Ten elements up |
| PgDn | Next window-full of text | Make right edge of text visible | Ten elements down |
Note: The effects of Ctrl-PgUp and Ctrl-PgDn can be seen only if the value window is narrower than the text and not wrapped. The cursor position is not changed by these keys; if you put it at the beginning of the line and then press Ctrl-PgDn, the cursor will seem to disappear because it has scrolled (horizontally) off the left edge of the value window. Try putting the cursor in the middle of the text.
