GUI Keyboard Shortcuts

The most reliable cheatsheet is the live one inside DUSTrack: click the Keyboard shortcuts button in the workflow panel’s Utilities group, and a modeless dialog opens with every binding that’s currently active, grouped by section (Annotation / Frame navigation / Layer-label / LK-interpolate / View / File / Other). Each button in the sidebar also shows its shortcut suffix (e.g. the Refresh UI button reads Refresh UI (f5)).

A static reference for the most common shortcuts is below — the live cheatsheet is authoritative when the two disagree.

Annotation

Key	Action
`0`–`9`	Switch to label 0–9 in the current layer
`Shift+,` / `Shift+.`	Cycle through extended label ranges (`10`–`19`, `20`–`29`, …)
`s`	Save the current layer to disk
`c`	Copy current label’s annotation from overlay to current layer at the current frame
`Alt+C`	Copy annotations at all frames of interest from overlay to current layer
`Ctrl+Alt+C`	Copy annotations in the selected event interval from overlay

Frame navigation

Key	Action
`←` / `→`	Previous / next frame
`,` / `.`	Step backwards / forwards (larger step)
`m`	Toggle current frame as a frame of interest
`Alt+,` / `Alt+.`	Jump to previous / next frame of interest

Layer

Key	Action
`-` / `=`	Cycle current layer
`[` / `]`	Cycle overlay layer (or set to `None`)
`v`	Run LK interpolation on the current label at the current frame

LK interpolation (event interval)

Key	Action
`z` (first press, over a trajectory plot)	Mark interval start
`z` (second press)	Mark interval end
`a`	Run LK-RSTC interpolation for current label across the selected interval
`Alt+A`	Run LK-RSTC for all labels in the interval

View

Key	Action
`r`	Reset view. Hovering over the image pane → resets image zoom/pan. Hovering over a trajectory plot → resets time axis to full video range and autoscales y to visible data.
`Alt+R`	Reset trajectory plots to the data extent (zoom to the annotated region).
`F5`	Refresh UI — re-render all annotations from `.data`. Recovery affordance for direct REPL mutations.
`Ctrl+C`	Copy the entire DUSTrack window (sidebar + image pane + traces) to the clipboard as an image.
