Users should have the ability to enter [gloss] items that match
dictionary entries and automate populating other tracks with data
[primary use-case is hand data]. The dictionary should be user-
growable: it should be possible to select a set of annotations and
assign them to a new [gloss] entry.
For example the user could enter the data for hand shape,
orientation, location, and movement for the sign "house", select all
or some of these data and assign them to a gloss template item
"house". Then they should be able to enter "house" into the gloss
field and have the templated hand values put into the transcript.
See the SRS and SDD for more details.
