Mapkey to activate current window

Hallo,

anyone knows, in Creo Parametric, the code to insert in the config.pro file in order to have a mapkey that activates the current window (just like Ctrl+A)?

I would like to replace the Ctrl+A with just one keyboard button (like, in my case, the button "<").

I tried to record a mapkey clicking the button "activate" but it activates always the same window.

thanks
