If you want the actual characters, this will take you to the next
occurrence:
/[""]/
In other words, put the two quote marks within square brackets.
If you want the troff sequences, use
/\\([lr]q/
The help text is at
:h /[]

" -> \(lq ... " -> \(rq
Hi,
The troff has infected me! :)
Troff distinquishes between the "opening"
double-quote and the "closing" double
quote by using \(lq nad \(rq instead.
I could think of a non-100% safe regex
to detect opening and closing ", but
this would miss in one or the other
case.
Is their a function or anything else,
which would allow me to write someting
which get closer to 100% error free
detection of opening and closing "
in vim?
...or may be, my regex fu isn't that
bright?
Cheers!

The big advantage of hjkl navigation is that it leverages
the home keys for touch typing on a QWERTY keyboard for
what is for many people the dominant right hand. Under
this system and with right hand at the home key positions:
index finger (j)umps down,
middle finger (k)limbs ups,
slide index finger left and (h)urtle left--(h) hangs near (j),
ringer finger to (l)eft of middle finger (l)urches left
Others have already said that "j" looks a bit like an
arrow down symbol, so I used to use this to remind myself
when it was new to me.
Honestly for me, the big reason I learned to rely on hjkl
navigation, had naught to do with being an old-timer
before marked arrow keys and everything to do with playing
Roguelike games such as Angband and UMoria using the
roguelike key command set:
https://rephial.org/help/playing
In such games the arrow keys work, but it saves time not
needing to reach for the arrow keys then hunt and peck for
the letter keys. Essentially, this is the same reason to
use hjkl navigation for text editing.
There is certain elegance to being able to call legacy
game play "training" with a modicum of seriousness. :)

I have never seen any use-a-world-map mnemonic tricks for vi / vim
before. It really is very where-you-are centric. For me, Jakarta and
Hong Kong are roughly the same direction, and Los Angeles is south.
Kamchatka is very much north-west instead of north. I could substitute
Klondike, Alaska, and Jalisco, Mexico for north / south. Maybe Lithuania
for east. Hong Kong works fine for west, even though it is really
south-west.

As others pointed out, whatever memory trick works for you, use it.
With the h j k l keys near the middle of the most used Latin keyboard
layouts, not only QWERTY but also AZERTY and QWERTZ, h is the leftmost
of them and l the rightmost. For the other two, what I use is this:
lowercase j has a downward-pointing tail and lowercase k has an
upward-pointing one.
Also, now that all keyboards have arrow keys, Vim supports them; but
this means that in Normal mode, j and ↓, k and ↑ are synonymous. I
defined the following mappings to have ↓ and ↑ move by screen lines
while j and k move by file lines (which is different when 'wrap' is
on):
" move by screen lines with ↑ ↓, by file lines (Vim default) with k j
" but not in Insert mode, where hjkl insert a letter
:map <Up> gk
:map <Down> gj
Best regards,
Tony.
