Title:
Wrong Escape Sequences for Home and End keys
Status in linux package in Ubuntu:
Expired
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 ...
