Android keyboard and remapping the CTRL key

Android keyboard and remapping the CTRL key

I have an Samsung Galaxy 10.1 running Android version 4.1.2. I am using
ssh to remotely connect to my main machine which runs Ubuntu 12.04 LTS.
Once I am connected I do all my work in emacs 24.3. I also have a
bluetooth keyboard.
My question is about remapping the Caps-Lock key to function as the Ctrl
key. I do this with my main machine by changing a setting in the terminal
options. I checked the options in juiceSSH and there appears to be no
equivalent. Perhaps there is a general way to do this with Android or the
Bluetooth Keyboard.
How can I remap the Caps-Lock character to function as the Ctrl character?
If you need more information let me know. Thanks in advance!
