#Marks

A mark flags a moment in a test, tagged by a test program as it ran or by a person, live or later. Marks show on the Replay scrubber and charts; [ / ] jump between them.

#Reading a mark

Shape says who made it; fill says whether it finished.

A mark is an instant (one glyph) or a span (a glyph plus an underline with end caps). A span that never closed, such as an aborted run, shows as a dashed band with no end cap, running to the edge of the window. A mark that ended in an abort is drawn in the alarm colour.

Crowded marks collapse into a count chip (12). Click it to zoom to that group.

On the charts, a mark shows only on the channels it is about. A mark about the whole run shows on every chart.

#Filtering

The tags button in the transport bar counts the marks in the window and opens the tags drawer:

To find a mark by name over a longer window, open the tags tab in the left panel and type in Filter tags. Click a row to move the playhead there.

#Marking a moment yourself

1. Shift-drag the scrubber to select a range, or put the playhead on the moment.
2. Press tag beside the clock (Shift-drag opens the form for you).
3. Type a name in tag name (sample-taken, anomaly) and press Save. The form shows what it will mark: the dragged range, or at the cursor instant.

The mark appears once it reaches the cloud, usually after a short delay. Until then the row says tag saved — appears when it lands.

#The anchor — t = 0

Count time from the moment that matters instead of clock time. Alt-click any mark to make it time zero. A dashed 0 line appears on the scrubber and every chart. The clock adds a second line with the offset from that moment (-3.2s, +41.0s). The status row shows the anchor (t=0 start); its × clears it. The anchor lasts for the session.
