Source

The Source tab displays the tags and values in the .hco file for many of the settings you selected, or for which you took the defaults, in the connection editor. As you make changes on other tabs in the connection editor, the tags and values displayed under the Source tab change to match.

You can also make changes to the tags and values in the .hco file directly by editing the source under the Source tab, and they will be reflected on the appropriate tabs of the connection editor.
