Built-in Custom Key Creation (this feature is not in Promo Trainers)

To create a custom key, make sure you have pressed F1 to activate
the trainer. Next, mouse over the option description on the
trainer and press the left mouse button. You will hear "Select Key".
Select the key on your keyboard that you wish to use. The program
will then say "Activated" and the option listed on the trainer will
update to the key you selected and will have "Custom" before it.
You can also click ANY option with the mouse button and then press
the ESC key to reset the trainer options back to their default
keys. You will need to do this each time you start the trainer or
use the Trainer Customizer described below.

Alternatively, you can also use our Trainer Customizer to accomplish
this! Download it from our trainer troubleshooting page (link below).
