Better shortcuts to navigate and edit tracking data.

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.

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

Selection

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.

Navigation

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.

Editing.

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.
