When you see that ${V%X*} and ${V#*X} appear in a pair for the same
variable V and same delimiter X, it almost always indicates a bug
waiting to happen.
What's the definition of "key" here? A member of known set of short
tokens, all of which consists only of alphanumeric, or something?
Even if you do not currently plan to deal with a value with '=' in
it, it may be prudent to double '%' above (and do not double '#').
Style: indent your shell script with tabs.

Indent your shell script with tabs; case/esac and the labels used
for each case arms all align at the same column.

Likewise.
