Subject: bug#16214: Consistency in dired-, occur-, and grep-mode
Date: Sat, 28 Dec 2013 18:57:16 +0900 (JST)

Dear Juri,

Thank you for the reply.  Current proposed keys are summarized in
Table 1.  Honestly, I am not capable to improve *Occur* and even I do
not know how I proceed for the next step including technical aspects
as described on www.emacswiki.org/emacs/BzrForEmacsCasualDevs.

Could you give me a suggestion?

Best regards,
Tak
