Dear Orgers.
This is a novice for novices post. Probably all of you here know this, so please
bear with me with patience and understanding.
Since new users are welcomed to this humble and warm community, I'd like
to share a (to me) hidden pearl.
After some time using Org, I just... ehem... (cought)... <miniscule>did
the tutorial</miniscule>.
I found it quite useful, and the main thing are the emacs movement
keys. Of course, they are not the standard keyboard keys like [home],
[end], [Pg down] or [Pg up]. That not only would be too simple (we could
brawl on that, really), but I believe the real reason is that those keys
were not available or standard when Emacs started.
The good news is that the equivalent keybinds are central in the
keyboard, so you don't even have to move your hands a bit off where they
are.
All in all, the effort to change muscle memory in Emacs makes sense only
if you have an obsessive compulsive maximizer disorder, like many of us
here, and use mostly Emacs (same thing again). ;)
Please note, I'm only saying "I found this and believe it useful for
some" and not "everyone should re-learn how to move". It doesn't make
sense to start any personal, opinionated and context dependent war.
In short, here is the compressed version in a org table.
--8<---------------cut here---------------start------------->8---
| | move | move | del | del |
| object | prev | next | back | forw |
|-----------+------+------+-------+------|
| text | M < | M > | - | - |
| screen | M v | C v | - | - |
| paragraph | M p | M n | - | - |
| sentence | M a | M e | - | M-k |
| line ↑ ↓ | C p | C n | - | - |
| < > | C a | C e | - | C-k |
| word | M b | M f | M-DEL | M-d |
| char | C b | C f | DEL | C-d |
C-l clear screen and redisplay all the text,
moving point to center, top and bottom of the screen
C-/ Undo
--8<---------------cut here---------------end--------------->8---
For those with visual memory, the image attached may provide some clues:
it's the same thing but the M and C keys are colored, so the pattern is
easier to see.
BTW, there is a quite clear and well thought pattern here:
+ sArt and End
+ Previous and Next
+ Forward and Backward
+ Kill
+ Backspace (DEL) and Delete.
I hope this may prove useful for someone there. :)
Best...

Yes, these bindings are very useful. And did you know that even
outside Emacs you can move/delete wordwise by pressing ctrl togeter
with the right/left arrows or delete or backspace? I only learned it
a few months ago. I learned it in [1], even though this wordwise
movement/deletion also works outside LibreOffice as well.

However, in my Emacs, backward-paragraph is bound to M-{, not M-p, and
forward-paragraph is bound to M-}, not M-n. M-n and M-p are undefined
here, except in specific modes (the only one I remember is the
minibuffer). Have you bound these keys yourself? Here I use Emacs
25.1-rc2. I confirmed with a vanilla session (invoked by emacs -Q).

I'm always surprised by how often C-a/C-e and M-f/M-b work in programs
that aren't Emacs. Of course there is probably some historical reason
behind this (as much as I'd like to think Google and Slack had emacs
users in mind).

Yes! At least it works in the command line. :)

I've always envisioned a collection of "You know you're an Emacs user
when..." for instances where this *doesn't* work out so conveniently.
Like how many times I've C-y'd out of habit expecting to paste and
nothing happens!

Yes, that's how I did it since I have memory and today is the standard.
Crtl and up/down in many editing programs means paragraph previous and next also.
That's why I was so surprised when I learnt that Emacs is courteous to
them, but it's native keybindings were different. :)

You're absolutely right, it is my fault, I forgot that I bind them!
What you have is the standard, this was just to follow the same pattern
that in the rest of the keybindings (Meta key, Previous and Next).
The standard binding (just replace the row) is
| paragraph | M { | M } | - | - |
Sorry to all of you, I did it some time ago and just forgot it.
