[WT-support] SO2R key binding for rig focus move

[Dominic Baines]

Thanks Bob,

Makes perfect sense. No / over 7 as UK keyboard.
I will have K1EL keyers on rigs independently. As using a cut down
version of K1XM SOR2Rduino to just swap the TX and audio while using
win-test for the logging only. Will not be a high rate use
