Today I learned that #konsole has built-in #ZModem support. Why's that cool? You don't have to start a separate scp to transfer files. Say you're ssh'd to some remote box, and there's a file you want to copy of. Just type "sz filename" and Konsole pops up a box asking where to save it. Or you can type "rz" and Konsole will ask you what file you want to send. Nifty.

#screen and #zssh also have ZModem support for features akin to this, though it's easier to have it right in your terminal.
