That tells me that your aterm (don't say xterm if your using aterm, by the
way) is interpreting the keys correctly, and passing the appropriate
escape sequences in response to the keys.
In a terminal window, you must remap those keys (which have keysyms in X)
into some sequence of characters, since that is all you have available to
you when playing with simple text interfaces.
The sequences normally chosen for all this stuff is as per the VT100 or
newer terminals. They don't, any of them, have a HOME or END key. A pure
VT100 don't have any of those funny extra keys between the typewriter keys
and the numeric keyboard.
However, the VT200 and newer series have FIND, INSERT, REMOVE, SELECT,
PREVIOUS and NEXT. In your case (which I believe is pretty normal), the
programmers chose to map the HOME key to FIND (which is CSI 1 ~) and
SELECT (which is CSI 4 ~).
The fact that you *see* the tilde, or in csh, CSI 1 ~, means that the
shell don't care to interpret them.
So, your problem is one of two things:
1) You shell simple are not able to handle these keycodes.
2) You've said that you have VT100, or similar terminal, whch don't have
any key sending the sequence CSI n ~
Start by telling the system that you have an aterm (or xterm, if aterm
isn't known). If that don't help, try saying that you have a VT220 or
similar. *Don't* say you have a VT1xx! And don't say you have some silly
terminal type which have no capabilities at all. The system might actually
If that don't help, try a modern version of a shell know to have some
advanced screen and keyboard handling for a long time, such as tcsh, or
