That's even older than the other sources of information...

-  The order in which the four files are searched (none of them myem(need)

-  variables (i.e. mytt(export) commands), since they are passed on to

   The only file you can alter which is started with every zsh (unless
   you use the tt(-f) option) is tt(.zshenv), so this is a good place to \
