How do I open a member in browse mode?

I need to open some source members in browse mode, so as not to lock
members that others are responsible for. I finally found
Window->Preferences, then Workbench->File Editors. But these settings seem
to have no effect on items in RSE perspective, only in Project perspective.

Another matter - when I try to Add... an editor to the Associated editors
list, the list of internal editors does not even inlclude the CODE Editor.
It does include the LPEX Editor. I would like to see both CODE Editor and
CODE Browser added.

I found I was able to add the latter 2 editors with External editors and
browsing (CODEEDIT and CODEBRWS didn't show up as registered file types - I
might have a Windows problem).

Now if only these would work in RSE.

Thanks
