Our setups seem to differ in some way. What I see with AltGr (not Alt) is Þ, with shift it's þ (this is Thorn; you are seeing eth) It seems that your left alt isn't doing Meta and mine does or something :) [...] > > The behaviour [of Alt-Shift-P] is the same if I do "ESC P".

I tried to describe what it does, and yes, this matches the behaviour pretty well: readline (I suppose) prints a colon (I guess this is meant as a prompt), you may enter some string, and then it searches back in the history for the last matching command -- so like an incremental backward search without the incremental bit :-) > Anyway, all of that's an interesting tangent, but I still don't get > a "freeze" in xterm from any of this. Absolutely.

Now curious as to what Van Snyder gets :-) Cheers -- t
