Cursor Controls
The LAPS software utilizes a highlighted cursor to make
selections from menus and to select fields within screens
that are to be operated upon. The cursor can be moved using
the standard terminal cursor control keys, which are <back-
space>, <up arrow>, <down arrow>, <left arrow>, <right
arrow>, <page up>, <page down>, and <delete>.
For PC computers which do not have these particular keys
or have only some of them, a set of cursor control com-
mands are supported. Each of these commands is effected
by holding down the <Ctrl> key while pressing a command
key. The available commands are listed in the following
table. These commands may be freely mixed with the use of
the normal cursor command keys at the user’s discretion.
