[Tex/LaTex] Using many typewriter fonts in a single document

Question

Reading topics about monospaced fonts, I found out that changing \tt font for the document requires replacing only one line in the preambule. For example, I only change the commented line

\documentclass[a4paper,11pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
% PLACE NEW FONT
\begin{document}
Default
\input{test.tex}
\end{document}

to \renewcommand

• \renewcommand{\ttdefault}{cmtt} for Computer Modern Typewriter
• \renewcommand{\ttdefault}{cmvtt} for Computer Modern Typewriter Proportional
• \renewcommand{\ttdefault}{lcmtt} for Computer Modern Teletype L
• \renewcommand*\ttdefault{lmvtt} for Latin Modern Typewriter Proportional
• \renewcommand{\ttdefault}{pcr} for Courier
• \renewcommand*\ttdefault{txtt} for TXTT

or \usepackage

• \usepackage[ttdefault=true]{AnonymousPro} for Anonymous Pro
• \usepackage{ascii} for Ascii
• \usepackage[scaled=0.82]{beramono} for Bera Mono
• \usepackage{courier} for Courier
• \usepackage[scaled=1.04]{couriers} for Scaled Courier
• \usepackage{DejaVuSansMono} for DejaVu Sans Mono
• \usepackage[defaultmono]{droidmono} for Droid Sans Mono
• \usepackage{inconsolata} for Inconsolata
• \usepackage{kpfonts} for KP Monospaced
• \usepackage{lmodern} for Latin Modern
• \usepackage[zerostyle=d]{newtxtt} for New TXTT
• \usepackage[ocr-a]{ocr} for OCR-A Optical Character Recognition Font A
• \usepackage{ocr} for OCR-B Optical Character Recognition Font B
• \usepackage{pxfonts} for PX Fonts
• \usepackage{tgcursor} for TeX Gyre Cursor
• \usepackage[scaled=1.05,proportional,lightcondensed]{zlmtt} for Latin Modern Typewriter Z
• \usepackage{luximono} for LuxiMono (needed getnonfreefonts luximono)
• \usepackage[scaled=1.05]{ulgothic} for Letter Gothic (needed getnonfreefonts lettergothic)

In the test.tex I simply use {\ttfamily ... } and I get selected font instead of default \tt.

What should I do to use the all listed above fonts in the same document?

The idea is something like this

\begin{document}
Default
\input{test.tex}
% Switch to AnonymousPro
\input{test.tex}
% Switch to ...
\end{document}

If you want to run a test document which includes the typewriter font alongside other styles (e.g. to test how well a particular typewriter font works with a serif used for body text) or you just don't like typing, this example provides a couple of commands for convenience:

\documentclass[a4paper,11pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\newcommand*\ttfontstotry{cmtt,cmvtt,lcmtt,lmvtt,pcr,txtt}% add additional families here, separated by commas
\makeatletter
  \newcommand*\myttfontstest{% defines the actual test command
    \@for \xx:=\ttfontstotry \do {% loops through the families
      \par family: \xx\par
      \renewcommand*\ttdefault{\xx}%
      \input{test}%
    }%
  }
\makeatother

\begin{filecontents}{test.tex}% just for testing
    ABCDEFGHIJKLMNOPQRSTUVWXYZ

    abcdefghijklmnopqrstuvwxyz

    Oh, jinxed quartz of black sphinx, go hear my vow!

    {\ttfamily
      ABCDEFGHIJKLMNOPQRSTUVWXYZ

      abcdefghijklmnopqrstuvwxyz

      Oh, jinxed quartz of black sphinx, go hear my vow!}

\end{filecontents}


\begin{document}

  \myttfontstest% try them out!

\end{document}
