Generate matching Regex

Input Lines one alternative per line; add /p at the end to generate all word permutations
Regex 0 alternatives
Substitutions (word alternatives)
If a line contains the left word, the generator also considers versions where that word is replaced by any right-side alternative. Multiple-word alternatives keep their original order by default. Add /p at the end of an alternative to generate only its internal permutations; this does not enable permutations of the whole input line. Add multiple alternatives per word. You can add and remove rows.
