jump next previous - tag bookmark or search

jump next previous - tag bookmark or search

[Adam]

My file of code is long and getting longer. So I would like to jump either
forward or backward to the next or previous section start, with a single
keystroke, such as F7 (previous) and F8 (next). 

I would be happy to comment each section start with a signifier-comment,
such as  ;; **    whereas all other comments would start ;;; or ; 

So, which would be more applicable to bind to F7 F8 for this ?  

Tags,  where it would be handy I suppose to collect the comment text on just
that line. 

Bookmarks,  although the need for an individual Bookmark name is
undesirable. 

or a backward or forwards search for ";;** " 

While it would seem the Search method most appropriate, I would be
interested in hearing any thoughts, comments or recommendations.

This sounds like a case for outline-mode or outline-minor-mode to me.
You probably have to adjust some regexp to recognize your sections.

Libraries commonly use a page separator (^L) for major sections. Then, you
can navigate among pages using `C-x ]' (forward-page) and `C-x ['
(backward-page). You can of course bind F7 and F8 to these commands.

To insert a Control-L character (^L), use `C-q C-l'.

Be aware that a page separator can also affect printing.

Maybe you just need to add a page break with `C-q C-l' then jump from
one page to another with `C-x ]'.

Checkout outline-minor-mode.

The Elisp coding conventions say that ";;;" starts a section heading (which
is recognized by outline-minor-mode).  I.e. normal comments should use ";;"
or ";" but not ";;;".
