xterm copy-n-paste and mouse selection in scroll back

[Bill Moseley <moseley@hank.org>]

I guess three questions about xterm (or something that will do this):

1) is there a way in xterm (or is it in X?) to copy to the clipboard? 
Not the PRIMARY (highlight & paste with center mouse), but rather the
CLIPBOARD (copy somehow?? and paste with shift+insert).

2) Is there a way to select an area with the mouse that extends up past
into the scroll-back buffer?  Say if you have a long listing that
scrolls off the screen, but you want to copy all that to the clipboard
(either one).


3) Do any of the xterm clones allow searching the scroll-back buffer?

These are all things I got really used to using with the Windows ssh
client SecureCRT.

Thanks,
