[NTG-context] stack words for explanation

Hi, i would like to write an FAQ for maritime distress radio. The spoken words and the "variables" should be highlighted in a nice way. What would you suggest me to do in context? My first idea a bracket or stacked words like this example: MAYDAY MAYDAY MAYDAY THIS IS TITANIC TITANIC TITANIC \--- ship name 3 times----/ Whats your idea? -- Jonas Stein
