Do you speak vi ?
=================

Vi's grammar is its greatest strength.  The grammar is what makes those
awkwards commands "logical".

Let's start with a simple example:

    This is a wrong elephant line.

"elephant" has nothing to do here. We should delete this word. so bring your
cursor at the beginning of the word (on the first 'e') and press "dw". The word
is now deleted. What does this command mean though? You probably guessed:

"dw" stands for (d)elete (w)ord.

And all commands in vi follow the same pattern:

    <verb>[adjective]<noun>

That's wah I call a "vi sentence". This syntax applies to _ALL_ vi
commands in normal mode. No exception.

What about those verbs/adjective/nouns now. Here is a (non-exhaustive) list:

verbs
-----
* d - delete
* c - change
* v - visualize (select)
* r - replace
* y - yank

adjectives
----------
* i - inner
* a - around

nouns
-----
* w - word (text, separated by special chars like space, dash, dot, comma, ...)
* W - WORD (text, separated by space or tabulation ONLY)
* _ - lines ('l' was already taken, unfortunately)
* { - paragraphs
* " - text in double quotes

There is more, obviously. But let's play around with those at first, and find
the meaning of these normal-mode commands:

	(c)hange (i)nner (w)ord

this will delete the inner "word" your cursor is on, and enter in insert mode so
you can change it.

	(v)isualize (a)round (")quotes

this will select the text between the ", AND the quotes themselves (inner would
not have selected them).

	(d)elete (_)line

This would delete the entire line.

Something worth noticing about this, is that Bill Joy decided to alias
"repeating" verbs perform the action linewise, because developper mostly act on
lines (copy/pasting bunch of code). So this is why "dd" will also delete the
line, "yy" yank the whole line, and so on.

I hope this will help you understand better how vi works. By understanding
this, you'll be able to perform action, and create commands you've never used
before in an easy way.
