19We've found it's useful to have a quick reference of Hoon's syntax always at
20hand. So above is a download link to a Hoon cheatsheet .pdf. It's missing a
21few of the literal syntaxes, but it covers the most common ones.
23This doesn't list any of the Ford runes, although there is now at least
24some documentation for those [here](../../tutorials/internals/ford/runes).
26The following runes also exist, but are currently undocumented and not listed in
27the cheat sheet:
29```
30!: :: turn on debugging printfs
31!. :: turn off debugging printfs
32!; :: using the "type of type", emit the type for an expression
33!, :: emit AST of expression
34$* :: bunt (irregular form is *)
35^. :: use gate to transform type
36^& :: zinc (covariant) -- see the docs on advanced types
37```
39Hope this helps!
