What terminal emulator do you use ?
warp: I prefer Terminal.app, mostly because it uses the OS native keys for copy/paste (cmd-c, cmd-v).  On windows I use putty which has keyboard paste on Shift-Insert.  On linux I use gnome-terminal which has keyboard copy/paste on Ctrl+Shift+C and Ctrl+Shift+V.  (I should stop using all three of these operating systems... :)
