_spacebar_ on one area: fullscreen the area
L: change colors
X: remove colors
double click one neuron: select the neuron
ctrl-mousewheel: zoom in/out
right-click: center clicked area
A great thing to do is to choose a few neurons (double click on the colored parts in the top-left, top-right, bottom-right windows) and then view the automatic 3d model by using _spacebar_ on the bottom-left window. Press _spacebar_ again to return to the normal view.
