I think I more or less understood what the thread was about, but thanks anyway for the clarification. Of course navi-mode does not offer semantic search within an Org-mode buffer. But for practical purposes it might be worth mentioning that typing one digit between 1 and 8 and then C-s or C-r in the *Navi* buffer lets you already search easily only in the headlines of an Org file. And many other views on a file are possible, that can then be searched by standard commands. With keyboard macros and switching between original buffer and *Navi* buffer (and using org-mark-element e.g.), a lot can be achieved without the need of writing any elisp code. -- Cheers, Thorsten

I would suggest C-c s instead. Using the global keymap also simplifies the initialization. In order to put the key definition into the org-mode-map, the map has to be defined already, i.e the define-key has to be done *after* org is loaded; so you can't put it in an arbitrary place in .emacs. The safest way is to put it in a hook (a list of no-argument functions that are executed after the mode is set on a file): (setq org-mode-hook '( (function (lambda () (define-key org-mode-map (kbd C-M-h) (lambda () (interactive) (org-agenda nil s ) ; maybe followed by more functions in the list ) ; this paren end the list ) ; this paren closes the setq Putting it in the global map instead bypasses this problem completely since the global map is defined before .emacs is loaded. That's not to say that the global map is always the right place to define a key: on the contrary, most of the time it isn't. But in this case it is the right place *and* putting the key definition there is simpler. -- Nick

Just to give you two examples: 1. type 'E' in the *Navi* buffer and the buffer is put in *Navi-Edit* mode, i.e.you can edit the headline in the *Navi* buffer and all edits are immediately applied to the associated Org-mode file. This is perfect for runnung Emacs keyboard macros only on the headlines of an Org-mode (or outshine) buffer. Type 'C-c C-c' to go back to read-only *Navi* mode. 2. with point on a headline in the *Navi* buffer, type 'e' and the subtree at point will be offered for editing in a temporary Org-mode buffer. This makes no sense for an .org file, of course, but is great when you structure your source code files (e.g. Emacs Lisp files) with headlines and use outshine.el, because then you can write all comment sections in Org-mode instead of as outcommented text in a source code buffer. -- cheers, Thorsten
