I was wondering if there is a way to hook into the column titles in the "All Posts" admin page to modify them. For instance, I would like to change "Post" to "
<strong>Headline</strong>". Are there any hooks that would let be do this without modifying the WordPress core code?
I have found some information about adding columns and modifying custom post type columns, but I could not find any information on modifying the columns that are standard in the "All Posts" screen.
