The key-bindings used in the MaMuT viewer can be customized through a text file, that allow you to remap any command to any key. To so, create a text file named mamut.properties in the Fiji.app folder (where the plugins and jars folders are). This file must follow this syntax example:
A=add spot
ENTER=add spot
D=delete spot
E=increase spot radius
Q=decrease spot radius
shift\ E=increase spot radius a lot
shift\ Q=decrease spot radius a lot
control\ E=increase spot radius a bit
control\ Q=decrease spot radius a bit
...
It follows the syntax key=command, one per line. Modifier keys such as ⌃ Ctrl and ⇧ Shift are specified by prepending the key with their name, separated by a space escaped with a backslash \. Spaces in commands do not need to be escaped. The dash # character at the beginning of a line is used to insert comments.
# The key bindings for MaMuT viewer windows.
# Available actions are the following (space in between words must be included):
#
# add spot
# delete spot
# increase spot radius
# increase spot radius a lot
# increase spot radius a bit
# decrease spot radius
# decrease spot radius a lot
# decrease spot radius a bit
#
# semi-auto tracking
# toggle linking mode
#
# show help
# toggle brightness dialog
# toggle interpolation
# toggle fused mode
# toggle grouping
#
# toggle source visibility 0
# toggle source visibility 1
# toggle source visibility ... up to 9
#
# align XY plane
# align ZY plane
# align XZ plane
#
# next timepoint
# previous timepoint
# step time forward
# step time backward
#
# No space around '='!
# An action can have several key bindings.
# When using shift, control, etc... use a a backslash-space after the modifier
# (as in 'control\ Q').
