<br>
I need to do some work on a system 3000 miles away. No problem <br>
connecting to it with ssh or setting X11 forwarding, but the delays are <br>
such that my usual editor (nedit) spends far too much time redrawing to <br>
be useful. Resizing a screen is particularly painful.<br>
<br>
Are there any X11 GUI editors that are less sensitive to these issues?<br>
<br>
If not I will just use nano or vim.<br>
<br>
Thanks,<br>
