Hello Dave
This is actually a developer issue, to connect the help button to the
right Help page in the wiki.
With the local help package installed, the Conditional formatting dialog
opens file
/text/scalc/01/0512.xhp
see
http://vm173.documentfoundation.org//text/scalc/01/0512.html?
I am trying to assist with the Help facility, using meta-bug 80430 as a
reference to items which require attention. My first attempt was look
at: https://bugs.documentfoundation.org/show_bug.cgi?id=55212 "UI: Help
and Help button in Conditional Formatting dialogs give empty page"
It's not clear
