Zoom the replay bar, View all and trip focus

How to

1. On History, turn the mouse wheel over the replay bar, or use its + and − buttons; on a phone, pinch the bar.
2. Zoomed in, the knob moves in tiny steps, so you can go through a short stretch moment by moment. Drag the bar to move along the day.
3. The View all chip, or a double tap on the bar, shows the whole day again.
4. Tap a trip in the summary chip's list: the bar becomes that trip, from its start to its end, and play stops at the trip's end.
5. The trip stays in focus when you tap the map or elsewhere; View all, another trip, another day or another vehicle ends it.
6. With the fuel graph open, the graph shows the same stretch as the bar.
