As you�re filling in the fields for a new specimen, you can type less and save time by using category codes as shortcuts. Most codes are a single letter or number, although some codes can be up to 6 characters in length.

To use a code instead of typing the full text, simply type the code followed by the <Tab> key to advance to the next field. Leaving the field causes the spell-checker to be triggered which looks for the code in the list of possible categories. If found, the full text is placed in the field. If not found, the text is considered to be �free-form� text rather than a code and is left alone. The spell-checker places a red line under the free-form text to alert you -- this can be ignored if your intention was to use the free-form feature.
