how to unhide the account

[Free BSD]

Dear List members

this is my first post to the list -- hope it will go through.

I have installed and trying to use gnucash in FreeBSD. I have clicked on
the hide button on one of the accounts, and now I cannot find any way to
unhide it. I have tried the documentation, and have googled around for
nearly two hours -- no luck so far. Is that a one-way process? I mean,
generally the concept is you can tuck away an account until you need it,
but then again there should be a way to unhide it when you need it, right?

any pointers or suggestion is most welcome

Happy new year to you all
