This excerpt about _getk is from a well-known source (I'm not going to repeat
myself...or have I already done so?)

"_getk (4A18h): ASM equivalent of getKey in TI-BASIC.
  
 Output:

  OP2 is the result if a key was pressed, otherwise 0.  The result is the same
that getKey    
   returns, check the Ti-manual for values."  

Don't ask me...
