How to include a bunch of tex commands globally

[Dr Eberhard Lisse]

That will not survive LyX Updates.  Local Layouts should go into the
local layout difrectory (which on the Mac is below ~/Library/Application
Support/LyX-2.3).

Never mind that "must be located" is incorrect.  LaTeX finds documents
in many places (find out what texhash does :-)-O)

I don't understand the issue, however. Why do you need (look at) the
TeX files generated by LyX? And even if so, why the concern about the
"clutter"?

That's what the Preamble is for (put in ton's of LaTeX and never look
at it again :-)-O)

I have a large include.tex for my handbook whih is included by the
master document and all child documents, so I have the same
"environment" for all and even setting up conditionals so font changes
depending on Landscape vs Portrait and similar.

greetings, el
