The list of key names is found in the header file
<filename>X11/keysymdef.h</filename> (remove the
<literal>XK_</literal> prefix). Note that due to limitations
of X11 shifted keys must be specified as a shift key
followed by the key to be pressed rather than the actual
name of the character. For example to generate "{" the
expression <literal>Shift_L|bracketleft</literal> could be
used (assuming that you have a key with "{" above "[").
</para>
<para>
You can also specify keys in decimal (prefix #), octal (#0),
or hexadecimal (#0x). They will be interpreted as keycodes
unless no corresponding key name is found.
