The specific type of INDUSTRIAL strength velcro strips I prefer using are called 'snap mount' or 'dual lock' velcro fasteners because BOTH sides of the velcro strip are the same, and self mating into each other for a solid interlock. This proves far superior to standard velcro. On my Tyros and PSR2000, I use this type of velcro to attach a portable halogen light(Littlelite)

Works great. I'm not worried about having to remove it because it's functionality will be immediately appreciated by future keyboard owners as well I'm sure.
