Take a clicked word into the box the cursor is in

GrabIntoFocused puts text in whichever box has the cursor, whatever kind of
value that box normally holds. It is what N1MM's digital window does on
Ctrl+click, for the exchange element the contest has no box for.

The entry window also says when a CQ has gone out, which the digital window
needs to clear its grab list on: a run that starts again brings new callers.

GrabList.N1mmDepth is the ten calls N1MM's grab window holds.
