Thank you for the response.

I see. It sounds reasonable <RET> to be assigned to the primary
purpose. Following is when I think that to assign <RET> to
(open-file-this-window) is convenient.
1. On edition of <file-a> in a single window, I feel like
referring to sentences in a different file.
2. (grep) something, then *grep* pops up in (other-window).
3. I will find a line in file-b; move cursor to the line on *grep*
4. Hit <RET> then <file-b> pops up on the first window
5. The buffer <file-a> disappears then I lost.
Now I know that I have to prepare the third window before hit <RET>!
Assigning <RET> to (open-file-this-window) on occur/grep may loose
convenience, but helps new users because that behavior is similar to
following hyperlink in a web browser. After exercises, one can lean to
hit `o', which actually is more easy to type than <RET>. How do you
think about <RET> with considering new users?
Let me focus on dired/occur/grep with four functions (A-D) for
now. Proposed keys are summarized in Table 1.
A. edit-buffer
B. open-file-other-window
C. open-file-other-window-no-select
D. open-file-this-window
A. edit-buffer
To avoid overwriting `e' in dired, it seems that `C-x C-q' is the
second choice. Is `M-e' or `M-g e' better?
B. open-file-other-window
As you mentioned, add `o' to (compile-goto-error) will do it.
C. open-file-other-window-no-select
Same thing, add `C-o' to something like (compilation-display-error)
will do it.
D. open-file-this-window
Other candidates besides <RET> would be something like `M-<RET>' or 'M-o'?
Tak
