For years I've used the eightBitInput: false X resource with xterm.
This is because my shell (tcsh) has emacs key bindings, and it lets me
quickly edit the command using emacs key strokes like "M-f" and "M-b" to
go backwards and forwards in a line. This feature lets me configure
the terminal to send "Esc" for Meta followed by the modified key (e.g.
M-b sends "esc b".)
Since I installed b68 today, it seems this no longer works. I don't
know why. (The meta key does work, because Emacs running with its own
X11 frame responds properly to it.)
Interestingly enough, dtterm has an analogous feature called "kshMode",
which works, except it uses the "Alt" key stroke instead of "Meta".
As an aside, one of my ancient, longstanding complaints about
gnome-terminal, and the reason I refuse to give up using xterm (to this
point anyway) is that it does not offer this configuration option.
(Neither does KDE's terminal, I believe.)
If anyone has any insight into what happened to my "Meta" key
translations in xterm, I'd love to hear it. (And if anyone has any
insight into how to get this feature added to gnome-terminal, I'd like
to hear that too. I wonder from time to time if gnome-terminal might be
less expensive due to shared implementation than xterm... .but maybe not.)
