...using a foot switch to key everything, either with or without a
sequencer, is the way to go IMO, although it can 'get lost' in a Rover
environment.  I prefer foot switching everything, whether I be on SSB or
CW.  Leaves the hands free for other things and can prevent unhappiness
from relays sequencing when they shouldn't.

Mash the pedal, then talk or send CW.  Gives everything a chance to cycle
to where it's supposed to be.  Having a quick reaction sequencer that keys
the radio last pretty much guarantees RF only when you want it.
