Moved some "see alsos" to the top menu.
=== Commands and Arguments ===
* [[Commands with KeyVal arguments|Commands with Key=Value arguments]]: For things like <code>\command[thiskey=thatvalue]</code>.
* [[Commands with optional arguments]]: One or more optional arguments within brackets.
=== Programming Techniques ===
* [[Processing Lists]]: Processing lists of values.
The newly defined command <tt>\!test</tt> can of course only be called upon when we are in the <cmd>unprotect</cmd>ed state, otherwise TeX reads the command <tt>\!</tt>, followed by the word <tt>test</tt> (and probably complains loudly about not being in math mode). These protection/unprotection commands can be nested. When the nesting becomes deeper than one level, the system reports the current protection level. It is a good habit to always start your macro files with <cmd>unprotect</cmd> and end them with <cmd>protect</cmd>.
