Note that you have to use "f" to get to the first #+ that belongs to a heading.

Restriction lifted.

Doable by defining these functions on your own:

    (defun set-keyword-next ()
      (interactive)
      (worf-keyword "NEXT"))

    (defun set-keyword-done ()
      (interactive)
      (worf-keyword "DONE"))

After a call to `set-keyword-next`, "j"/"k" will move by "NEXT"
keyword until any other command is called.

I think I see what you mean, but `helm` is already good enough in my
opinion.

I have mixed opinion of `ace-jump-mode`: on one hand it's fast, on the
other - it always requires you to focus and read: it can never become
muscle memory.

`helm`, on the other hand, is very nice in this respect: if you want
to go to a heading related to "ice cream", you just

1. Press "g" for go.
2. Type "ice".

    This will usually give you just one candidate to you can "C-m"
    right away.

    If you're an ice enthusiast and there are many
    matches (from 2 to 10), use "C-n"/"C-p" to select.

    If you're obsessed with ice and there are more than 10 matches,
    press space to narrow the candidates and type in something else:
    "ice age" will match not only the movie, but "Aged rice" as well.
    This should bring you to less than 10 matches.

This also works nicely with org mode: "todo coffee :office" will match
a TODO related to coffee with tag :OFFICE:.

Hopefully it's not a thousand.  Actually the whole "Knj" thing was my
attempt at minimizing the amount that you have to remember. I don't
know much about vim, but I've glimpsed its notion of verb-modifier-object,
at least the modifier-verb part: "Kn" is the modifier
(keyword-next) and "j" is the verb (down).  Or "4" is the modifier (4
times) and "j" is the verb etc.

You don't have to remember each combination together, you just have to
remember the components and combine them as you like. So my suggestion
for you is consider not defining `set-keyword-next` and binding it to
some random free key binding, but using "Kn" for a while, maybe it'll
grow on you.
I can think of one more use for "Kn": "Kn+" could add a heading with
keyword "NEXT" ("+" is the verb to add an empty heading).
