I only notice that behaviour if I leave the keys unmapped. If I reassign them then that seems to be permanent, with no dual functions.
I did notice that after loading my old hot keys pref file, I had several with the dual function. eg I use X to toggle xray, and it took a while to work out why grid snap kept getting turned on. Once I removed X from grid snap and toggle xray (press and release) and then reassigned to toggle xray it seems to be ok.
Its not the first time I’ve seen maya choke on old prefs. In this case it seems fixable though.
