[senit] "Press any key" Keyboard Access

Hi

We have a child with Rett Syndrome who can sometimes access a computer very
effectively using either a switch or a plasma screen. However, her motor
planning skills are very variable and sometimes neither of these access
methods are very effective for her. Her class teacher has found that the
most consistently reliable way for her to access the computer is when using
a "press any key" keyboard access method. 

Does anyone know of a way of using "any key" on the keyboard to register as
a switch press? 

Hopefully.
