Does urxvt support user defined keys?

[Mun]

Hi,

I'm using Gnome and miss the konsole terminal from KDE.  The one
feature I miss most of all is konsole's .keytab file where one can
define a sequence of characters to be entered for a single key press.
For example, I could define F8 to be "Hello, World", and if I pressed
F8 that string would be entered as if I typed it myself on the
keyboard.

Someone mentioned I should try urxvt, but from a scan of the man page
I cannot tell if a keytab-like feature exists in urxvt.  Can you let
me know if this functionality is present with urxvt, please?

Regards,
