You can use a mouse with SCO Shell if you are working at the console
and the appropriate hardware has been connected to your system.
SCO Shell expects you to have a three-button mouse (although you can
work with a two-button mouse as well). Mouse buttons are numbered from
left to right. You can move around the
screen area freely; when the mouse cursor is positioned over an
item, you can press one of the buttons to achieve the following effects:
Button 1
Equivalent to pressing <Space>; typically moves to the
next item in the current group. For example, if you press
button 1 while the mouse cursor is on the menu, the cursor
jumps to the next item; if you press button 1 while
the mouse cursor is on a window containing a list, the window
scrolls up or down (depending on whether the cursor is in the
upper half or lower half of the window).
Button 2
Equivalent to pressing <Enter>; typically activates the
current item. For example, if you press button 2 while
the mouse cursor is on an application in the Application list
window, that application is activated.
Button 3
Equivalent to pressing <Esc>; typically aborts the
current operation or returns to the previous level of a menu.
If you have a two-button mouse, you lose Button 1's
functionality; use the <Space> key instead.
