This package provides only two macros viz. \TheKey and \TheValue to define then use pairs of key/value and gives a semblance of a hash. Syntax: \TheKey{key}{value} to define the value associated to the key, does not produce text; \TheValue{key} to return the value linked to the key. Both arguments of \TheKey are ‘moving’ as LaTeX defines the term and we have sometimes to protect them.
