Is there a straightforward way (via defadvice or otherwise) to change the focus behavior

  • 0

Is there a straightforward way (via defadvice or otherwise) to change the focus behavior of buffers such as help, grep, occur? In particular, I would like to modify the behavior of M-x occur to take me to the *Occur* buffer directly. Some modes (e.g. ESS) provide finer-grained control over the display of such “temporary” buffers, but is there a general strategy for buffers where such controls aren’t provided?

    (add-hook 'occur-hook (lambda () (pop-to-buffer occur-buf)))

(add-hook 'help-mode-hook (lambda () (pop-to-buffer (get-buffer "*Help*"))))

(add-hook 'grep-mode-hook (lambda () (pop-to-buffer (get-buffer "*grep*"))))

    A general approach, as an alternative, is to use special-display-regexps or special-display-buffer-names to make such buffers special-display, which puts them in a separate frame (and selects it). E.g.:

    (setq special-display-regexps '("[ ]?[*][^*]+[*]"))
