Control dual color bar

OtherConfigured target requireddual-color-bar.control

Capture a small region, track a dual color bar, and send left or right keys in one high-frequency node invocation.

Example use

Configure the target region, inner/outer color ranges and left/right keys to keep a narrow pointer near the wide target bar.
