Keyboard Scrolling

• SCROLL - one window down
• m-SCROLL - one window up
• s-SCROLL - one window right
• m-s-SCROLL - one window left

These seem to work only when keyboard input is active. It won't work during Disk wait for example.

Mouse Scrolling

Clicking in a scroll bar

• Middle - Move the top/left side of the scrollbar to the clicked position
• Right - Move the top/left line of the window to the clicked vertical/horizontal location in the screen
• Left - ???

These seem to work even when the SCROLL button won't.
