How do I put raid target icons in chat?

Although extremely annoying when people use them to spam trade, inserting icons into chat can be very useful for certain situations, especially for party/raid leaders (even tanks leading groups who want a macro that says “skull first, then x, sheep moon”)

The easiest method for me is to put the name of the symbol in curly braces as such: {skull}
You can also reference them by number, which can save space in macros but is less clear what each icon is: {rt8}

The full list of icons are:

• {Star} / {rt1}
• {Circle} / {Coin} / {rt2}
• {Diamond} / {rt3}
• {Triangle} / {rt4}
• {Moon} / {rt5}
• {Square} / {rt6}
• {Cross} / {X} / {rt7}
• {Skull} / {rt8}
