To switch fast between one keyboard language and another the easiest way is to simply create a hotkey that runs the command to switch the keyboard, for that, edit your hotkeys file:
You have a small description of how to modify this file on the start on it, scroll down and you will see some examples, now go to the end and you can add something like this:
KeyDown CA 1 exec setxkbmap fr
This entry will use the combination Ctrl + Alt + 1 (number one of your keyboard) to switch to the french keyboard. Add another one for your other desired keyboard or as many as you want. Save the file and reload Enlightenment to start using it (with Ctrl + Alt + End)
You can use any combination of your choice, and you can add any keyboard option to the exec command, you can also run the command directly from a terminal to see how your keyboard changes (you must open a new terminal every time to try it), check "man setxkbmap" to know about more keyboard options.
