Yes. Type the co-ordinates into the position display at the top of the map screen and a green go button will appear press that button. Look in latest Manual page 4 App Layout.

Aren't "Grid References " and "Coordinates" two different things ?(though a grid reference is derived from a coordinate).

There are geodetic/geographic coordinates (lat/long based on GDA 94/2020) and MGA 94/2020 grid coordinates (based on UTM zones)

Yes - but what about the term "grid reference"? As stated, different. Dare I say... Google it :)

May come across as pedantic....but

UTM, a grid system, Military grid reference system, both available in ExplorOz Traveller can be done as Dick has described.

Don't get your point Greg. The standard term we used for UTM coords was a grid reference if that's what you mean, but they are still coordinates. Pretty sure you know but others might be interested in section 7 of this ICSM document:

ICSM Grid Ref

p85 has the Universal Grid Reference box typically seen on National Mapping (et al) large scale UTM topo maps (also usually present on GA 250K and 100K geological maps iirc).

As you know, in the UTM system LL coords can be derived from UGRs, and UGRs can be derived from LL coords

I don't know how EOT operates but grid coords require a zone ID as well as the northings and eastings

Military grid reference is the term used by EO Traveller, also the term used by all my soil surveyor colleagues.
