Search in the source? In 2020 it's at the top of the Contents panel.
sorry, I may not have clearly clarified my issue. I have the TOC pane open, I wish to locate a particular page within the TOC - I can not find a Search feature specific to the TOC searching.
There was a Find option in the RH2015 TOC but it does not exist in RH2019 or RH2020 - at least not where it was in RH2015. Opened TOC pane, right click on any topic within the TOC listing and there was a Find Topic issue. This does not exists in RH2019 or RH2020. Only options available are Edit, Rename, Duplicate, Delete. the Find option is not available.
received reply to a separate inquiry with the details, this issue can be closed.
go to Contents tab > Search for the topic > Right- Click the topic > Locate in TOC
