    1.29 -standard key events (of type EEventKey, see the TEventCode enumeration). It 
    1.30 -also causes key events that turn the FEP on or off to be consumed. If the 
    1.31 -FEP is simulating key events, or is off, no key events are consumed (so that 
    1.32 -all are passed on to the underlying application) and the macro returns with 
    1.33 -EKeyWasNotConsumed.
