The most common computer control commands have been added to your device as insertable tools so you no longer have to type a whole string of characters to generate the command. You can just insert the correct tool for the command.
When you use any storing procedure, you can use the OUTPUT MACRO button after using the INSERT TOOL key. OUTPUT MACRO opens up a page with a list of all the computer control commands.

For example, if you select the ALT key, you will see the following:

This command also includes the PROMPT MARKER. Depending on what you are trying to achieve, you may want to delete the SERIAL ON command. However, it is much easier to delete one or two elements than to type in the whole string.
If you do not see the command you want, you will have to create it yourself. All the keyboard commands for IBM and Mac computers are listed in the Computer and Mouse Commands Article
