<P>
Regular expressions may be entered in six ways:
</p>
<UL>
<LI>By typing in the regular expression window;</LI>
<LI>By copying the contents of the clipboard from the file menu;</LI>
<LI>By loading the contents of a file from the file menu;</LI>
<LI>By recalling an entry from the <a href="#historylist">history list</a>;</LI>
<LI>By inserting components from the <a href="#palette">palette</a>;</LI>
<LI>By inserting components from the <a href="#charclass">character class palette</a>;</LI>
</UL>
<a name="charmap"></a>
<P>
The ability to copy the contents of the clipboard is particularly important
for those who wish to make use of a wide range of characters. Unicode characters
can be selected and copied to the clipboard using a Unicode character map.
Here we see the <a href="http://gucharmap.sourceforge.net/">gucharmap</a>
in which the Japanese <i>hiragana</i>
range has been selected. The character お has been selected and inserted twice
into the text region at the bottom of the window. Pressing the <i>Copy</i> button copied
the string おお to the clipboard.

The command <i>Load Regular Expression from Clipboard</i> on the file menu
will then insert the selected characters into the regular expression window.

Here we see the result of matching this regular expression against a large Japanese lexicon.
