eclare on "[Plugin: Ultimate TinyMCE] Can't write polish letter "ź" [alt+x] inside the visual editor"

Having the same issue here. Alt+X is a shortcut for making a SPAN tag around selected text. It works even if you disable that button in the Ultimate TinyMCE settings. As there's no way to turn off keyboard shurtcuts that I know of, you can try to find the shortcut code yourself and delete it. I've been looking around for it but don't see it.
Josh, please remove this keyboard shortcut code, it affects all Polish people :)
