1) Install xclip and xdotool

sudo apt-get install xclip xdotool

2) Make a file myscript.sh

mkdir ~/bin

gedit ~/bin/myscript.sh

3) Copy paste this script into it

#!/bin/bash

TEXT="[email protected]"

printf '%s' "$TEXT" | xclip -i -selection clipboard

xdotool key --clearmodifiers "ctrl+v"

4) Make the file executable

chmod +x ~/bin/myscript.sh

5) Make a shortcut

Settings -> Keyboard -> Shortcuts -> Custom shortcuts -> click [+]

• Name: anything, Command: /home/USERNAME/bin/myscript.sh
  
  
  
  
  • Replace the USERNAME with your username
  
  


• Click on the Disabled text and then press your magical keystroke. For example Ctrl-Shift-S


• You may have to restart unity with setsid unity or by logging in and out to make the shortcut work. (at least i had this bug on Ubuntu 13.10)

Troubleshooting

If you have any problems with pasting the text. Try changing xdotool key to xdotool sleep 0.5 key. It gives you time to take your hands off the keyboard before xdotool tries to press "Ctrl-V"
