Oh, that was not clear from your original question. One easy solution 
would be to reconfigure the user interrupt (Alt-.) to bring up the 
emergency evaluator. Just change SystemDictionary>>handleUserInterrupt 
to bring up the emergency evaluator. That could be controlled by a 
preference. You might also bring up a tiny interface similar to the 
primitiveError screen where you can choose to continue with the default 
interrupt handling or drop into the emergency evaluator. Or, if you 
want to get fancy, check the time since the last user interrupt, and if 
it was less than a second,bring up the evaluator. Best of both worlds 
:-)

There might have been a goody for this some time ago, I can't quite 
remember though ...

Oh, here it is: http://swiki.gsug.org/sqfixes/1802.html
