Shortcuts for editing and navigating the main view of TrackMate

The TrackMate tool config panel

When a TrackMate session is running, the Fiji toolbar displays a new tool specific to TrackMate.


This tool must be active for the shortcuts displayed below to work. By ‘active’, we simply means that it must be selected.

Double-clicking on the tool icon will bring the TrackMate tool config panel:


The following tutorials exemplifies how to do manual curation or editing of tracks, where these shortcuts and tools are used:


Key / Mouse Action
click inside a spot Select the spot.
shift + click Add / Remove from selection.
click and drag Draws a freehand ROI. All spots in the current frame inside the ROI are selected.
shift + click and drag The spots across all frames inside the ROI are selected.
Key / Mouse Action
/ When a spot is selected, navigate within a track, forward and backward in time.
/ Within a track, move across siblings. That is: move to a spot that belongs to the same track within the same frame. For instance: across two daughter cells after a cell division.
/ Navigate across tracks.
f / g Change the time-point currently displayed. Move backward / forward in time, by an amount specified in the TrackMate tool config panel.


All editing commands require the mouse to be placed inside a spot. No need to click.

Key / Mouse Action
a Add a new spot at the mouse location.
If the auto-linking mode is on, the new spot is automatically linked to the spot currently selected, and the new spot becomes selected.
d Delete the spot at the mouse location.
q / e Change the radius of the spot at the mouse location. Make it smaller / bigger.
shift + q / e Like above, but with greater amount of changes.
l Toggle a link between two spots in the selection. There must be exactly two spots selected, and they need to be not in the same frame. If a link already exists between the two selected spots, it is removed.
shift + a Start semi-automatic tracking for the spot in the selection. The parameters for semi-automatic tracking can be edited in the TrackMate tool config panel.
shift + l Toggle auto-linking mode on / off.
