In the future, please refrain from filing so many issues at once.

• Standardized on Apple-Up/Down for Page Up/Down. Does not change selection.
• Standardized on OA+SA+Up/Down for Home/End. Does change selection.
• Modified clicks are ignored.

Look over this issue, issue #690, issue #691, issue #692, issue #693, issue #694, issue #695 and issue #696 and also add support for the "Page Up", "Page Down", "Home" and "End" keys on extended Apple Desktop Bus (ADB) keyboards on the Apple IIGS:

"Page Up" key: Implement support for this key wherever Apple-Up Arrow is currently implemented or proposed to be implemented.
"Page Down" key: Implement support for this key wherever Apple-Down Arrow is currently implemented or proposed to be implemented.
"Home" key: Implement support for this key wherever Open Apple-Solid Apple-Up Arrow is currently implemented or proposed to be implemented.
"End" key: Implement support for this key wherever Open Apple-Solid Apple-Down Arrow is currently implemented or proposed to be implemented.
