Cryptick supports a way to make definitions, indicators, and fodder available as help options for solvers.
[[Definition]]
Place double square brackets around the bits of your clue that are definitions.
{{Indicator}}
Place double curly brackets around the bits of your clue that are indicators, usually placed next to pieces of fodder.
((Fodder))
Place double parentheses around the bits of your clue that are fodder for an adjacent indicator.
To make use of these options, mark them up in your clue as appropriate.
