The strip and the track
Along the bottom of the edit page is the strip: every take the cull handed over, as a row of cells, with the track under it. Between them they say where you are and let you move anywhere in the list with one gesture.
The strip
At the strip's left is its heading, Takes from the cull, with the count under it: 143 frames · 12 adjusted. At its right, a Shortcuts button and the same count the other way round, 12 of 143 adjusted.
Each cell is one take. The photograph fills the cell, and under it is the name of the look the frame wears (or its film simulation's name; a dash when it has neither). A take on which any of the eight tonal sliders (Exposure, Contrast, Highlights, Shadows, Temperature, Tint, Saturation, Vibrance) is off zero shows a small sliders mark in its top-right corner, and only those takes count as adjusted in the two counts above. A take that wears only a look, a crop, a curve, a mask or a spot clean shows no mark and is not counted. The take on the canvas is ringed in orange and drawn at full strength; the rest are dimmed.

Three notches double them; the size is remembered with the library, and the active take stays centred through the resize. A plain scroll still scrolls the strip. A⌘-scroll over the canvas is the canvas's own zoom, not the strip's.
The Shortcuts button shows a short reminder: Arrows move between takes · \ toggles before/after · double-click a slider to zero it.
The track
Under the strip is a thin bar, the track. It is the whole list of takes at once, however long the list is, cut into columns. On the edit page every frame is a take, so the columns read as one solid run, and they are the ground for the two marks drawn over them:
- The window — an orange band over the stretch of the list the strip is currently showing. It appears only when the strip is longer than the space it has.
- The head — a thin orange mark over the take on the canvas. The window says what is on screen; the head says where you are standing. On a long list those are rarely the same.
Press on the track and drag to scrub. The take under the pointer goes onto the canvas and keeps doing so while the button is held, and the strip scrolls to it at the same time, so the strip and the photograph never disagree about where you are. A plain click does the same for one spot.
Where you are
The top panel says 12 of 143 takes, beside Back to cull and the undo arrow. It counts the takes on this page, in the strip's order.
← and → step one take at a time, and so do the chevrons either side of the photograph. These move the edit page's own cursor only, so back on the cull page you are still on the frame you left, unless you decided a frame in between.
Press R and the take on the canvas is rejected and gone from the list: its cell leaves the strip, its column leaves the track, the count drops by one, and you land on the next take. ⌘Z puts it back where it was. A rejection also moves the cull's cursor, which Opening your takes in Edit explains.
