[1]Mrxvt is a great Unix/Linux/BSD terminal client. It is light weight
   and supports tabs. I'm still waiting for Unicode & UTF-8 support. If
   non-Latin support is more important than tabs check out
   [2]rxvt-unicode/urxvt. These are both based off of a beta of the
   wonderful but languishing [3]rxvt terminal.

   Anyway, one of the things I'm trying to do is make my various systems
   as keyboard consistent as possible. Mrxvt doesn't support keyboard copy
   and paste out of the box. I found [4]a post that details how to set it
   up.

   This tip makes use of my newest favorite CLI tool: [5]xclip. Here's
   how.

   On Ubuntu 12.04, install xclip:
sudo apt-get install xclip

   Then using your favorite editor edit (or create) the file
~/.mrxvtrc

   Add the following lines at the end of your file:
Mrxvt.macro.Ctrl+Shift+v:            Paste CLIPBOARD
Mrxvt.macro.Ctrl+Shift+c:            Exec !/usr/bin/xclip -o | /usr/bin/xclip -s
election clipboard

   Save the file and restart your Mrxvt.

   Viola!

   Let me know if this works for you. If you get this working under rxvt
   or urxvt, let me know!
