To assign a character, type in the desired command; then terminate
the line by pressing (ENTER) (or the character you specified with the
ENTER parameter). To skip a character, press (ENTER) at the prompt.
Pressing (ENTER) does not place an (ENTER) character at the end of the
key equivalent, but merely terminates your input for that key. To place
an (ENTER) character in a key equivalent, type a semicolon ( ; ) where
you wish an (ENTER) press to be executed. Each line can be up to 255
characters long.
When you have assigned all 26 characters, the file is closed and the
BUILD terminates. Pressing (CONTROL)(SHIFT)(@) terminates the BUILD
at any time.
If you want to create characters or strings that are not available from
the keyboard, use the (HEX) parameter of the BUILD command.
It is not absolutely necessary to use the BUILD command with the
IKSM extension to create a KSM file. The KSM/FLT program can use
any file in ASCII format. TRSDOS uses the same rules concerning
(ENTER) and the semicolon for a file in an ASCII format.
If you wish to deactivate the KSM filter, issue the command:
RESET *K I
(ENTER)
If you wish to change to a different KSM file, issue the commands:
RESET *K I
(ENTER)
RESET

Examples
A

DI
R :
0
(ENTER)
specifies the key equivalent of A as "DIR :0". The command DIR :0 is
displayed on the screen when the (CLEAR) and
00
keys are pressed
together. The command is not executed until you press the (ENTER)
key.
S= >FREE;
(ENTER)
specifies the key equivalent of B as "FREE;". A semicolon in a key
equivalent represents an (ENTER) character. So, when you press
(CLEAR) and (]J, the FREE library command is executed immediately
(since the last character of the phrase is a semicolon).
F = >FREE ; DEl.) I CE;
(ENTER)
specifies the key equivalent of F as "FREE;DEVICE;". A semicolon in
a key equivalent represents an (ENTER) character. So, when you press
