Hi Marek, well I guess you could assign the font name as the object name on the letters that you created.

To do that, after you have created the text, select it and click on the object name field in the properties panel, see item #1 listed at:
https://moi3d.com/4.0/docs/moi_command_reference11.htm#propertiespanel

If you do that then when you select that object later on that name will be displayed there.
