# Editor: Vim

Do this chanllege: <https://www.shortcutfoo.com/app/dojos/vim>

## Cheatsheet (that I don't know)

My bad habit (mostly motion):

* use `3j` or `3k` instead of hitting `jjjj` or `kkkk`
* Edit at the first of the line: `0i` **->** `I`
* Move to first non whitespace char: `0w` **->** `^`
* Navigation in current screen: `H/M/L` first/middle/last
* Scroll current line to top of window: `zt`
* `t` and `f` is different: `t` is to **before the character** where `f` **includes the character**. That's why when you copy to quote you should use `vf'` instead of `vt'` (this will miss the last character before `'`)

Good to use:

* Good to navigate based on error message:
  * Go to line number 12: `12G`
  * Go to column 20: `20l`
* Go to previous location: ` `` ` (two backticks)
* Use bookmark: `ma` (mark with a) then `` `a `` (go to a)

Good to know:

* Swap case: `~` (can do it in normal mode)
* move screen: `CTRL+e` or `CTRL+y`
* `:x` is same as `:wq`

## Cheatsheet

* `%`
* `gu` `gU`
* `*` `n` `N`

## Use Bookmarks

* set: ma
* go: \`a (go to exact location) or 'a (to go front of the line)

What can it do:

In-file navigation:

* Use bookmark: `ma` and then \`a
* or go to last place: \`\`

Delete text in multiple lines (block):

* go to start of block
* ma
* go to end of block
* d\`a
