Symbols and Words

When typing proofs or sentences, it’s often awkward to enter symbols. In the first-order language awFOL, you can use words as well as symbols (they are treated as equivalent). This makes typing easier. And since zoxiy recognises awFOL, you can use the words in logic-ex.
Here’s a table listing the words you can use for each symbol.
arrow, ->
double_arrow, <->
_|_, contra, contradiction
and, &
or, |, ǀǀ
all, every
some, exists
