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.
