If I use completion after I type Info- , I get a list of variables, none of which are Info-directory-list. If I try help .. v and type Info-directory-list, I get the current value and the doc-string which decribes using "customize-variable" etc. Does customize-variable allow you to use Info-directory-list on your system? It won't here, on the latest 21.0 and 21.2. I tried to use the variable via the .emacs file, but I could not find the syntax that would keep the existing values, and add one new value to the end. Thank you for all you do. Robert
