Description of problem: Some keys, including Home, End, and the left and right arrow keys had no effect when editing the hostname in anaconda's graphical installation. I was still able to type alphabetical characters and move the text cursor with the mouse. I don't know if any other characters were affected, or if the problem affected any other text editing fields.
I assume this is with F10beta? This is a known issue and has been fixed now. *** This bug has been marked as a duplicate of bug 461832 ***
