TO REMOVE ALL INDENTS ON A SELECTION :le

Cut and paste:

1. Position the cursor where you want to begin cutting.
2. Press v to select characters (or uppercase V to select whole lines).
3. Move the cursor to the end of what you want to cut.
4. Press d to cut (or y to copy).
5. Move to where you would like to paste.
6. Press P to paste before the cursor, or p to paste after.

Copy and paste is performed with the same steps except for step 4 where you would press y instead of d:
d = delete = cut
y = yank = copy

________________________________________________________________________________________

Another option which may be easier to remember would be to place marks on the two lines with ma and mb, then run :'a,'byank.

Many different ways to accomplish this task, just offering another.

........................................................................................

I had never found a satisfactory and re-callable way of doing copy-paste in vi, but this solution is really topnotch. Also, I added this to .vimrc "command! P :'a,'byank" to allow the "P" key to function as a shortcut
_______________________________________________________________________________________

just use V to select lines or v to select chars or Ctrlv to select a block.
When the selection spans the area you'd like to copy just hit y and use p to paste it anywhere you like...

_______________________________________________________________________________________


It sounds like you want to place marks in the file.
mx places a mark named x under the cursor
y'x yanks everything between the cursor's current position and the line containing mark x.
You can use 'x to simply move the cursor to the line with your mark.
You can use `x (a back-tick) to move to the exact location of the mark.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

One thing I do all the time is yank everything between the cursor and mark x into the clipboard.
You can do that like this:
"+y'x
NOTE: In some environments the clipboard buffer is represented by a * in stead of a +.

_______________________________________________________________________________________

You can copy/paste by using the + register (read more: Accessing the system clipboard)
"+gyywill yank a line, and put it into the + register. You can paste in your other window with "+p in normal mode, or Ctrl+r + while in insert mode.
If you don't wish to use split windows, there really is no other way to paste between windows apart from using the system clipboard.

  You can use vim tabs as well as split windows. – ostler.c May 30 '12 at 21:26

  It should also be noted that on Linux there are two clipboards - the regular clipboard - the one you access with CTRL+C and CTRL+V - is mapped to the + register. The other clipboard stores the last selected text and can be pasted with middle-click - and in Vim it's mapped to the * register. – Idan Arye May 31 '12 at 14:35

Since you already know how to cut/yank text, here are a few ideas for pasting it back into another file:

• Edit the first file, yanking the text you want. Then open your second file from within vi (:e /path/to/other/file) and paste it
• Open both files together in a split window and navigate between them using Ctrl + w, Up/Down either by:
  
  • vi -o /path/to/file1 /path/to/file2
  • From within the first file, Ctrl + w, s

Patrick Winston - How to Speak

 [from youtube comments section; notes by 'GRIG', edited by ek]

Start 

1. Do not start a talk with a joke.
2. Promise - Tell them what they gonna learn at the end of your talk.
3. Cycle – make your idea repeated many times in order to be completely clear for everyone.
4. Make a “Fence” around your idea so that it can be distinguished from someone else’s idea.
5. Verbal punctuation – sum up information within your talk some times to make listeners get back on.
6. Ask a question - intriguing one Place and Time
7. Best time for having a lecture is 11 am. (not too early and not after lunch)
8. The place should be well lit.
9. The place should be seen and checked before the lecture.
10. The place should not be full less than a half, it must be chosen according to the amount of listeners.

Tools 

For Teaching 
1. Board – it’s got graphics, speed, target. Watch your hands! Don’t hold them behind your back, it’s better to keep them straight and use for pointing at the board.
2. Props – use them in order to make your ideas visual. Visual perception is the most effective way to interact with listeners.

For Job Talk. Exposing, Slides 
3. Don’t put too many words on a slide. Slides should just reflect what you’re saying, not the other way around. Pictures attracts attention and people start to wait for your explanation – use that tip.
4. Make slide as easy as you can – no title, no distracting pictures, frames, points and so on.
5. Do not use laser pointer – due to that you lose eye contact with the audience. Instead you can make the arrows just upon a slide.

[notes here change in style, despite "hours" of work on GRIG's part(?)]

Informing

Show to your listeners your stuff is cool and interesting.
You have to be able to:

-show your vision of that problem
-show that you’ve done particular things (by steps) All of that should be done real quick in no more than 5 min.

Getting Famous

If you want your ideas to be remembered, Winston's Star:

* Symbol
* Slogan
* Surprise
* Salient
* Story

- Symbol (visual key to chest of information)
- Slogan (encapsulating idea engraved on chest)
- Surprise (common fallacy that is now no longer true--awe of opening chest)
- Salient idea (the one that sticks out--shiniest artifact)
- Story (how you did it, how it works, why it's important--where, what, why)


How to End

- Don’t put collaborators at the end, do that at the beginning.
- Question’s the worst way to end a talk.
- It’s good to end with a Contribution slide – what did you do in the talk? recap.
- At the very end you could tell a joke since people then will leave the event feeling fun and thus keep a good memory of your talk.
- Don't say "Thank you (for enduring this nonsense)." "I'm glad [reason]..." Offer praise for attention and a wish of well-being and benefit from the talk.
