I have noticed that since updating my websites to 3.3, using alt/option+delete on a Mac, (to go backwards deleting whole words at a time) no longer works within the post editor. It's driving me crazy as I used to use it All The Time and I've tried re-loading and fiddling about to make sure it isn't my computer, but no, it only happens when I'm editing a post in the specific post-editing box in WordPress 3.3. Seems to be broken for some reason unknown to my non-techie self. Can anyone help me to get it back, or tell me if it's broken for them, too?
PS using command+delete to delete the whole last line doesn't work anymore either in the post-editing box
