I never meant to file this bug against emacs24.

With alt-F2 I still see the command "ubuntu-bug linux" in the HUD.

On the bug website it then showed me Emacs24 - I then explicitly changed
it linux.

This bug report is to be filed against the linux package but after that
story I don't know how to do this anymore.

That's coincidences: read-char seemed to return <unspecified> today;
additionally the description of an escape sequence in XTerm's
ctlseqs.txt is wrong and when I - today - was in the bank it a bit
longer than usual or something and they told me: "Well, that's Computers
right? Ah, that thing is defunct ...". The pen and paper "program" still
worked, though.

>From ctlseqs.txt in package XTerm:

          Result is CSI  8  ;  height ;  width t
            Ps = 1 9  -> Report the size of the screen in characters.

It's not Ps = 19 but Ps = 18

Title:
  Wrong Escape Sequences for Home and End keys

Status in emacs24 package in Ubuntu:
  New

Bug description:
  Part of my current project involves "descrambling" the escape
  sequences sent by terminals for certain keys. As I was not able to
  find any documentation for the Linux VT (called tty) I choose to
  reference the VT100/220 documentation and I consider the following
  behavior a bug.

  - The home key (above your cursor keys or fn-left on a MacBook) sends the sequence: CSI 1 ~ which corresponds to some non-existent key labeled "Find"
  - The end key (fn-right on a MacBook) sends the sequence CSI 4 ~ which corresponds to some other non-existent key labeled "Select"

  These keys may have existed on the same position on the keyboard as
  our modern Home and End keys but according to the documentation they
  are not Home and End: http://vt100.net/docs/vt220-rm/table3-1.html

  The usual escape sequences for the Mac / PC Home and End keys are: CSI
  h for home and CSI F for end. Both the Gnome Terminal and the original
  XTerm do send these escape sequences.

  The easiest way to get out of the Terminal mess is probably a standard
  to be defined by the few implementors of Virtual Terminals left. But
  as long as an implementation doesn't document its capabilities and
  control mechanisms every behavior can be considered a bug.

  There are other key mapping related issues, too. Like meta on an alt
  key when Meta keys are there ...
