Sharon, I can see you are using the [] construct to a list, which I can use
with defvar or defconst when the latter two construct a list.

Then the solution would be

["Outline" dingo-outline-subm t]

where one uses a defvar list rather than a callable function as done in

["Hide Entry" outline-hide-entry t]
