This is an untested proposal: create a virtual figure and use its event 
handler sensitive to on-the-flight keyboard events:
* create a figure
* set its .visible property to "off"
* set properly its .event_handler and its event_handler_enable properties
* in the event handler function: catch the code of the event; if it's a 
keyboard event (or a specific one that you require from the user), issue 
an abort instruction;
