<code> </code>display the current abbreviations
<pre>Major Section: <a href="PROOF-CHECKER-COMMANDS.html">PROOF-CHECKER-COMMANDS</a>
</pre><p>

(show-abbreviations v w)
-- assuming that v and w currently abbreviate terms,
then this instruction displays them together with
the terms they abbreviate
show-abbreviations
-- display all abbreviations
</pre>

<pre>
General Form:
(show-abbreviations &rest vars)
</pre>
Display each argument in <code>vars</code> together with the term it abbreviates
(if any). If there are no arguments, i.e. the instruction is simply
<code>show-abbreviations</code>, then display all abbreviations together with the
terms they abbreviate.<p>
If the term abbreviated by a variable, say <code>v</code>, contains a proper
subterm that is also abbreviate by (another) variable, then both the
unabbreviated term and the abbreviated term (but not using <code>(? v)</code> to
abbreviate the term) are displayed with together with <code>v</code>.
