If you're replacing processing anyway, why not use "-z myinput"?

Well, if you really need to check if the user broke out of update, this 
works on 4.8:

=====
::declare Updating(1,*,g):
@update::Updating = "y":
::screen:
::end:
@entsel:::
:Updating = "Y":Updating = "" ; mesgbox "Left update with @SK = '" & @sk & "'":
::end:
=====

And, if your processing never uses POPUP within it, this can be simplified:

=====
@update::popup ("1","1") update - (@sn):
::mesgbox "You left update mode with @SK = '" & @SK & "'":
::end:
=====

Nit: The user never _sees_ that they have left browse mode.

See above.

However, since you're talking about breaking out of browse mode, and not 
update mode, why not just check for @SK="BRKY" in @ENTSEL?

=====
@entsel:@sk = "BRKY":mesgbox "@ENTSEL reached with @SK=BRKY":
::end:
=====

You still haven't said why you feel you need to modify field 5 from 
automatic.  Even if it were true that you couldn't check for BRKY in input 
processing, what does that have to do with your assignment to field 5?
