<pre>want after epsilon, so you don’t need to press <backspace> to delete it.
For example to write α+β you can type \alpha+\beta, and to write α⊕β you
can write \alpha\oplus\beta.

There is, as Luciano pointed out, a subtle difference between these<br>
two forms of input syntax:<br>
<br>
<ul>
<li><tt>\someLatexSymbol</tt> keeps the next character the user
typed (usually a space)</li>
<li><tt>\+161 </tt>replaces the character sequence in including
the space</li>
</ul>
<p>The rationale behind this – seemingly arbitrary – difference in
behavior is<br>
as follows:<br>
</p>
<p>The symbol input is meant for Smalltalk code and the operator
symbol<br>
must be followed by some white-space to denote a one-character
binary<br>
message selector. If you want to type a multi-character binary<br>
selector it also works nicely (See Luciano's explanation).<br>
</p>
<p>The input of arbitrary Unicode symbols works for every text
editor and is<br>
meant to enter Unicode characters, everywhere in the text,
possible in<br>
the middle of a word. It closely mimics the Unicode input<br>
methods of the those of many Unix X11 based programs,<br>
where you can type <tt>Shift-Control-U <hex digits ...>
space</tt>.<br>
