I do. I've been using UNIX for 18 years. I've used X for much of that time. I've even used actual vt100 terminals (although it was very long ago). I've worked on everything from Ultrix to DG-UX to Solaris to Linux and many more in between. Pressing the backspace key in all these systems generates a ^H character. The delete key generates ^?.

I know all about this issue; I've used Emacs for 14+ years. But, I want to know how to make backspace send ^H. it> If any environment by default sends ^H rather than DEL (i.e., ^?) it> when you press BackSpace, then you have to file bug against that it> environment.

So, should I submit bugs against Solaris, HP-UX, AIX, etc. etc. so that when I telnet to those systems from my Linux box my keybindings work properly, more/less work properly, vi works properly, etc. (luckily I use bash as my shell which has the very sensible behavior of treating backspace and DEL identically)? I think not. Linux is in the minority here and my preference is to change Linux to work the "traditional" way rather than customize all the others.

Yes, that's why I said "keycode 22" and "the backspace keysym". it> If you look down, you'll find that the keycode is said to be '"'. it> Of course, this is not really the case.

I don't understand this at all... the keycode for backspace is 22, not ^?, and xmodmap -pke doesn't generate output in quotes. Paul> Where should I look for the cause of this?

I use many different system types and, as I said above, it's far simpler for me to change Linux back to work like all the others than it is to try to change all those other systems and applications to work like Linux. it> There is an exception.

So, something changed in the rxvt/xterm builds? I checked all the app-defaults and couldn't find anything. Do I have to recompile them locally?
