Currently, I'm using org-id-get-create to generate a unique ID
for headings that I frequently go to in org-mode.
* Foo
:PROPERTIES:
:ID: F3B14102-A66D-408C-8833-1F9CF7E5047C
:END:
Then, I copy the newly created ID to the kill-ring,
and paste it into a block like this:
(global-set-key (kbd "<f6> f") (lambda () "Goto Foo Org File"
(interactive)
(org-id-goto "F3B14102-A66D-408C-8833-1F9CF7E5047C")))
This will map F6-f to jump to Foo.
I know that there are many ways to navigate org-files, but using the
ID is great because it requires only two keystrokes.
This works pretty good, except I'd like to improve three things:
1) I'd like to be able to see a menu of where I've mapped my shortcuts
2) I'd like to simplify the creation of these IDs and shortcut keys.
3) I have about 10 quick-keys now, so I have 30 lines of very similar code
I'm sensing an org-babel type approach where I could define an org-mode
table like this:
| Name | Key | ID |
| Foo | "<f6> f" | 123456779 |
Then, I could loop through the table, and for each row, I could
run this code:
(global-set-key (kbd <COLUMN 2>) (lambda () <COLUMN 1>
(interactive)
(org-id-goto <COLUMN 3>)))
Before I do something like this, I'd like to know if anyone's done something
similar or if anyone wants to chime in.
Thanks!

I've made some progress on this, and I've defined a table like this:
#+tblname:navigation-shortcuts
| Foo Org File | <f6 v> | 733BD03F-0938-432F-B59A-BE235A2DE7E2 |
| Bar Org File | <f6 b> | 123456 |
I would like to map a function that iterates over the items in the
table, and maps
the keyboard string in column 2 to the ID in column 3.
I tried something like this, but all I get is "Wrong type argument:
integer-or-marker-p, (quote (second shortcut-def))"
#+srcname: map-nav(navigation-shortcuts=navigation-shortcuts)
#+begin_src emacs-lisp
(defun map-navigation-shortcuts (shortcut-def)
(global-set-key (kbd (second shortcut-def)) (lambda () "Goto Foo Org File"
(interactive)
(org-id-goto '(third shortcut-def)))))
(mapcar #'map-navigation-shortcuts navigation-shortcuts)
#+end_src
Can anyone point out where I'm going wrong?
Thanks,

I haven't tried your code, but the way you call `kbd' is obviously
wrong.
`kbd' is a macro and does not evaluate its arguments; try
using `read-kbd-macro' instead.
HTH,

Stepan,
Thanks for your help -- The keyboard shortcut is now being mapped
correctly, but
whenever I press <f6> a, I get "Symbol's value as a variable is void:
shortcut-def"
I suspect that (lambda()) is not evaluating (org-id-goto (third
shortcut-def)). I need some way to do that.
I would really like to know an "acceptable" or "standard" way to
implement this feature -- I think it would help me a lot with learning
Lisp & functional languages. Any help is appreciated!
Here's my new code:
#+tblname:navigation-shortcuts
| Vim | <f6> a | 733BD03F-0938-432F-B59A-BE235A2DE7E2 |
#+srcname: map-nav(navigation-shortcuts=navigation-shortcuts)
#+begin_src emacs-lisp
(defun map-navigation-shortcuts (shortcut-def)
(global-set-key (read-kbd-macro (second shortcut-def))
(lambda ()
(interactive)
(org-id-goto (third shortcut-def)))) ;; this line is not
evaluated inside lambda()
)
Thanks,
--Nate

Hi Nathan,
when the lambda form is evaluated (when you press f6) the variable
shortcut-def doesn't exist any more.
The problem is that elisp doesn't support closures. See
this info page:
(elisp) Top > Variables > Variable Scoping > Extent
As a workaraound you can save the table in a global variable with setq
and access that variable in the lambda form.
Hth,
Stephan

Another way would be to use `lexical-let' from the CL package, i.e.:
(global-set-key (read-kbd-macro (second shortcut-def))
(lexical-let ((shortcut-def shortcut-def))
(lambda ()
(interactive)
(org-id-goto (third shortcut-def)))))
should do what you want.

This is very cool!
Here's the final source code for defining shortcuts to headings in
org-mode files, if anyone's interested:
* Fast Navigation to Files
:PROPERTIES:
:ID: FC8A103B-5959-4A13-9735-F175C36CDC01
:END:
- Create an ID using org-id-get-create (See the :ID: in
the :PROPERTIES: for this heading)
- Put that ID in the table below, along with your favorite shortcut
sequence and a description
- See "Nav Shortcuts" below for an example
- Save oodles of time with your shortcuts, but waste the time
writing lisp code to implement the shortcut list :-)
#+tblname:shortcut-definition-list
| Appointments | <f6> a | A33F7A0C-F974-4C7F-A4FD-1AAA6CF9C60E |
| Foo Org File | <f6> f | F3B14102-A66D-408C-8833-1F9CF7E5047C |
| Home | <f6> h | 772DFBDD-38A3-4E92-8860-6904CC9D4F49 |
| Nav Shortcuts | <f6> <f6> | FC8A103B-5959-4A13-9735-F175C36CDC01 |
#+srcname: map-nav(shortcut-definition-list=shortcut-definition-list)
#+begin_src emacs-lisp
(defun map-navigation-shortcuts(shortcut-def)
(global-set-key (read-kbd-macro (second shortcut-def))
(lexical-let ((shortcut-def shortcut-def))
(lambda ()
(interactive)
(org-id-goto (third shortcut-def))))))
(mapcar #'map-navigation-shortcuts shortcut-definition-list)
#+end_src
