Keyboard Keys
Note: You must first run the MS-DOS utility, GRAPHICS.COM, to print graphic
displays; if not, only text characters are printed. See your MS-DOS User's Manual for
details.
You can press the Ctrl-PrtSc keys to toggle on the "echo" function, during which your
printer prints the currently displayed line of data each time you press the Enter key.
Cursor Control Keys
The four arrow keys move the cursor in the direction of the arrow: left and right one space
or up and down one line. With most applications if you press and hold an arrow key for
more than a half second, the cursor moves at a faster speed. You can adjust the speed
using the Setup Program described in Chapter 4 and with some application programs.
Pressing the Fn key with the arrow keys generates the functions shown on the front of the
keycaps: Home, End, PgUp, and PgDn. Some applications use the arrow keys for
different and additional functions; see your application program documentation for
particular arrow key functions.
Esc
The Esc (Escape) key is used in many applications to cancel a command, exit the
application, or introduce a special command called an escape sequence. See your
application program documentation for particular Esc key functions.
Ins
The Ins (Insert) key toggles on and off the insert mode in MS-DOS and many
applications. In insert mode you can move the cursor anywhere on the line of text and
insert characters, pushing existing characters on the line to the right. Press the Ins key
again to cancel insert mode, in many applications pressing other keys also cancels insert
mode.
