You don't state your situation or reason for this, but can't you just test in the KeyPress event for Esc and take appropriate action, such as NODEFAULT?

IF nKeyCode = 27  && Esc
    NODEFAULT
    && More code
ENDIF

Or in some other scenario could you test for LASTKEY() and take action?

IF LASTKEY() = 27  && Esc
    && Code
ENDIF
