<bmx-timeline-navigator>
A strip under (or over) a bmx-timeline showing all of its time at once.
The strip counts every release across five years; its window is the part the timeline shows. Drag the window, drag its edges, or click the strip. Tab to an edge and use the arrow keys (Shift moves the whole window).
Every property, event and method: https://docs.binarymission.co.uk/webcomponents/bmx/bmx-timeline-navigator.html
