Register shortcode with ESC to activate Visor

Hi team !

I am running TotalFinder 1.5.10.
For some reasons, I had to reset all my settings.
But now, I can no longer register ctrl + ESC (^+ESC) as a shortcut to activate Visor feature. I am sure it was possible before because I was using this shortcode for almost 2 years.

Is there any workaround to register this shortcode ? By editing some config file for example ?

Thanks in advance,
