Program Keys
Basically, "program keys" have meaning only to business programs that
are designed specifically to use them. However, these type of programs,
such as spreadsheets, are becoming quite common. Refer to the program
documentation to see if and how it uses the program keys.
Arrow Keys
-
These are also called "cursor keys." The
arrows on these four keys indicate the direction the cursor
will move when you press them. With WordStar, you can
either enter Ctrl-key commands to move the cursor for typ­
ing and positioning text, or you can get the same effect
much more simply by using these keys.
With many spreadsheets, these keys move the active cell
in the direction they point. Other programs use the arrow
keys in similar ways.
Each of the arrow keys has a second meaning when used
together with the right Shi f t key. The meaning appears at
the top of the key. (Again, for these keys to do what they
say they'll do, the program you're using must have been
designed with these keys in mind.)
Home
-
When using WordStar, pressing and holding the
right Shift key while pressing Home will move the cursor
to the upper-left corner of the screen. This is equivalent
to the " QE command. With spreadsheet programs, Home
usually puts the active cell indicator in the upper-left corner
of the spreadsheet (cell
AI).
End
-
When pressed with the right Shift key, it will put
the cursor in the lower-left corner or the most remote cell
on a spreadsheet.
Pg Up and Pg Dn
-
These are the "page up" and "page
down" keys. They move the cursor some set number of
lines upward or downward.
