While the primary annotations are done in the 'Slice Viewer' the information for the annotations can be seen in the segmentation panel. The tool creates a new segmentation group at the beginning after loading each patient. This can have unlimited numbers of individual segments are labels added to it.
In the slice viewer there are a few shortcuts which have been setup to ease operation and keep the labeling consistent.
The tool has been setup with Shift+(T, M, or N) shortcuts to annotate regions. The default tool is the 3D sphere paint brush with a very small radius of 8 pixels.
The segmentations are described in detail here. The default brush is the sphere, but there are many others which can be useful for segmenting larger or homogenous regions quickly.
