Reading the cluster means running down dozens of lines, and a single
click did the whole job — QSY, mode, callsign — so every line looked at
dragged the radio with it. One stray click while reading took the
operator off the station they were working.
Looking and going are two different intentions, so they are two gestures
now. The band map is unchanged: clicking a spot there is already a
deliberate act, not a way of reading a list.
