Well the question was for both save and tab, so leaving out tab isn't a valid way to make the answer shorter, and, = in the condition test section? arggh. That should have never been valid syntax. Even if we had distinct comparison operators vs. assignment operators, like == >= etc, there are no such common operators for co, etc, so, the most consistent way is to use the mnemonics always.

I think the question was not asked quite clearly in the first place either.

a) Surely you want to suspend the wlf processing no matter how the user leaves the field, which means back-tab and down/up arrow too, and Enter if the value didn't actually change.

b) Surely you only want to suspend the wlf processing _sometimes_, so the test needs to be on some other condition.


So I would say:

@wefxx: : sv = xx :
@wlfxx: other_condition and xx eq sv : end :

Not testing for escesc or tab at all.
