The lowercase l (el) and the number 1 are not interchangeable.

On a typewriter, the shift lock key locks all the keys into their
uppercase positions. On a computer keyboard, pressing the
Caps Lock
key changes only the alphabet keys to uppercase—
the number and symbol keys aren’t affected.
The Other Keys
In addition to the character keys, the computer keyboard contains
a number of keys that carry out special computer tasks. This sec-
tion describes these special keys.
❖
The 12 function keys (
F1
,
F2
, etc.) across the top of the
keyboard carry out program-specific tasks. To find out what
these keys do, refer to the program's documentation.
❖
The function of the
Ctrl
key (Control key) also varies according
to the program you're using.
❖
If you're in Windows, pressing the
Alt
key lets you open menus.
❖
Pressing the
Fn
key simultaneously with one of the specially
marked keys allows you to emulate a 101-key keyboard, turn
keyboard overlays on and off (page 275) and control various
system functions.
❖
If you’re using Windows 95, the
Win
key allows you to open
the Start menu.
❖
If you’re using Windows 95, the
App
key functions the same as
the secondary mouse button. Pressing the
App
key opens a pop-
up menu listing options featured in Windows 95.
Toshiba's powerful Fn-esse program allows you to assign your
own
Fn
key combination to launch a Windows program or docu-
ment quickly. Instructions for using this program are given in
“Starting Programs Faster with Fn-esse” on page 262.
