Code snippets in instructions are ambiguous

[kytrinyx]

One of the instructions for a String drill said:

Take this string and turn it into a symbol. The output should be :mouse:

Knowing beginners, there is reason to believe that they might expect the output to be :mouse: rather than :mouse.

Would it be worth adding backticks around code snippets to make it clear what is code vs what is English text?

UPDATE: I had to put backticks in the quoted text, because GitHub turns :mouse: into :mouse:.
