I've been playing with the keyboard script from
http://www.greywyvern.com and have a temporary solultion, that is until I can get around to making it into a full fledged plugin.
Unpack the attached and put the files into your template directory (including the image which goes into images/).
Enter the following at the bottom of your main.php:
<?php include(dirname(__FILE__).'/vki_attach.html')?>
Put it underneath:
<?php /*old includehook*/ @include(dirname(__FILE__).'/footer.html')?>
Then in script.js, at line 57, you will find:
var VKI_KBLAYOUT= 'hebrew';
Change 'hebrew' to whatever other language you need. You can only have one language keyboard at a time. So if you want to change languages, you have to change that line and restart the editor. I'm looking into how to change languages dynamically and might think of using it in fckgLite.
