help search

[Harry Putnam]

I wanted a way to revert the current session back to its state when I
started it.  I've made deletions I want back.  

Opening help and searching on `revert' shows a pointer to:
  gnucash-help/usage.html

I don't see a hit on revert so after scrolling a while I'm wondering
if I can search this huge page somehow.  I don't see a way provided.

Finally I quit the session without saving and restarted.  

Is there a more refined way to this?
