Why try?1. Successfully used as IDE by others.
2. Don’t need X enviroment (Production quick fix? No problem!)
3. Lightweight & fast.
4. Able to edit large files 50MB, 100MB, 1GB (Ok... search the 1GB file is
an horror but still is openable).
5. Code is written faster (with enough vim experience).
6. Your keyboard skills will be improved.
place of new recruits is to the proving ground
run shell command: vimtutor
training
Now time for ‘Missions’.They show practical tricks (at least I have hope that they are practical) or just examples how to
fight with vim.
Basics
● move: hjklweb$0gGf● edit: aiorxdvc● search: /nf● undo and redo: u, ctrl+r● copy & paste: ypdx

Macros
Armory
q - record macro (in fly!)
small but powerful
how to use macros1. find some ‘regularities’
2. record macro by q and pick an <register> (e.g. ‘a’ key)
3. work as usual with vim
4. stop recording by q
5. set cursor at next ‘regularity’ <number of repeats>@<register>

Last words
1. Vim is not better than other IDE's. It is different. There is advantages
and disadvantages e.g. I think native IDE will alwasy have better code
autocomplete.
2. Before grabbing a mouse, early try do it with keyboard. Power of vim
is: to be always ready for text typing.
3. Beginnings are difficult, but after time will appear the conditioned
response, in the other words copy&paste/movement/refactor will take
milliseconds.
Mission Accomplished
