I think that the key mapping for "," and "C-c," in agenda is a mistake and should be swapped. In the normal org-mode, "C-c ," is mapped to org-priority. In agenda mode this gets changed to org-agenda-show-priority. In agenda mode "," is mapped to org-agenda-priority, which behaves like org-priority. This is very confusing.
We should swap the mapping or find some other mapping for org-agenda-show-priority. That doesn't confuse the keystroke memory of users or introduce an inconsistency between modes. If agenda mode was all that we had to deal with, this would not be an issue. But it's more important to keep things consistent within org-mode. Sorry for missing any earlier discussion of this. I didn't notice a proposal to introduce keystroke meaning inconsistency within org-mode. This change appeared between 7.8.11 and 7.9. R Horn
