Pls help: How to assign the Fire Button (Left ALT key) as alternate Start Game?

[DeWe]

In the controller menu, there is the possibility to assign a 2nd key code for Start Game (Enter).

Now I've installed a RGB Fire Button (like Stern). During attract mode (where i can scroll and select one the the fantastic table), the fire button is lightning too in different colors. It looks nice, but the user want, about the light, used also this button to start/select a table.

The default configuration of VPX of the fire button ist "LEFT ALT" key (script "lockbarbutton"). Uncomfortable I can't  set this key in the controller settings. Is this an used / blocked key? Does this key, if it assigned,  make some trouble? Or how can I assign the keycode for the left ALT Key as alternate game start key?

Easiest would probably be to use Joytokey so the fire button presses the same key as the start button.

A keymapper should be a good idea in the fist moment, but it will be interference with the table. The firebutton is assigned as own button or on start-game or on one/two magsave keys.

It was hard to find the right default keycode for the fire button. In most of the old cases/ description  the 'Menu key' is mention as default. But this key doesn't work...
