All users with 10k+ reputation are given access to inline
edit tags link. This link is shown something like this(only on hovering) as shown in the image that follows.
But when I edited this post( https://stackoverflow.com/q/15586126/1190388 ) and decided to use the inline tag editor instead of editing using the post box itself, I did not see the
edit tags text. This is shown in the following image.
