Start with a Draw or Impress document. Open menu Format. You should see an item "Theme...". If not, use LibreOffice with a clean user profile. Go to Tools > Customize, tab "Menus", target "Format". You see an item "Theme..." (below the item "Bullets and Numbering..."). Its tooltip shows: Label:Theme..., Command: .uno:ThemeDialog, Tooltip:Theme Now search for "Theme" in the "Available Commands" list. Error: A "Theme" item does not exists. The user has no way to define a short cut for the command or the add it to a menu in case it is missing (which happened to me).
