I am trying to solve an obscure format difference between Japanese and
standard MS Word.

Standard MS Word allows search and replace on tabs using ^t, and
paragraphs using ^p. This feature is invaluable for reformatting large
blocks of text, especiallly for use in MSExcel.

Searches using ^ simply don't work in Japanese MSWord.
Either that, or there is something in the default setup which is
blocking it.

Are paragraph and tab markers searchable in J Word ? And if so, how ?

Google searches have produced no results, only a couple of possible
leads.
