Adding/Managing Keywords Seems to be very difficult.....

Question

Has anyone else noticed in iPhoto 2011 that managing keywords seems to be terrible?
If I add a keyword or delete it, sometimes it seems better to hit TAB when finished, but sometimes it's better to hit ENTER.  Sometimes when I need to remove a keyword, I highlight it and hit DELETE, then hit ENTER only to have it show right back up again.
When I'm in a Smart album, sometimes a keyword change will suddenly apply to ALL images in the album, and sometimes it will only apply to the few images I've got selected. 
Am I doing something wrong?  Is anyone else having these challenges?  Very frustrating.....

Oh no,  You should be able to edit them there. It sounds like there may be some damage to the library. First try this:  make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
     User/Home()/Library/Caches/com.apple.iPhoto folder.

3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
If that doesn't help Try this:  launch iPhoto with the Option key held down and create a new, test library.  Import some photos and check to see if the same problem persists. If you can edit the keywords in the Info tray  as  expected then your current library is damaged.  Post back if that's the case. 
If you can't edit them in the new library you may have to reinstall iPhoto. To do so you'll have to delete the current application and all files with "iPhoto" in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/  folder,

Then install iPhoto from the disk it came on originally.
