Defining and Using Your Function Keys
Defining and Using Your Function Keys
There are 32 function keys you can define for your use:
•
Function keys F1 through F16
•
Shifted keys SF1 through SF16 (hold down the shift key while pressing a function
key F1 through F16)
F16 is predefined as the TACL HELP key, but you can redefine it using the #HELPKEY
built-in variable, as described in the TACL Reference Manual.
You can create two types of function-key definitions:
Creating a Library File for Your Function Keys
To define your function keys, you create a library file that contains the function-key
definitions. Your library file is an EDIT file (file code 101). Create this file in your
saved default subvolume, using a text editor such as TEDIT. Give the file a descriptive
name such as MYKEYS.
For each function key you want to define, enter:
?SECTION
TACL directive that indicates the beginning of a definition.
function-key
Name of the function key you are defining. Unshifted function keys (F1 through
F16) or shifted function keys (SF1 through SF16).
type
Type of definition: ALIAS or MACRO. Other types of function-key definitions are
described in the TACL Reference Manual.
command
TACL command that you want this function key to execute.
Type Description Example
Alias Defines a function key as a name
for a TACL command or
application. Define the F1 key as an alias for the FILES
command; when you press F1, the TACL
program executes this command.
Macro Defines a function key to invoke
one or more TACL commands or
run an application. To specify arguments for a macro, enter them
on the TACL command line before you press
the function key.
