Practical Vim

每天一回一回的看，終於把Practical Vim看完了
不過到了後期，大部分就真的都看不太懂了＝＝
所以大多還是只記錄了前期我比較看得懂的一些 tip

Ch1: The Vim Way

. command: Repeat the last change
- Command in normal mode
- The insert mode between two normal mode

Intent	Act	Repeat	Reverse
Make a change	{edit}	.	u
Scan line for next character	f{char}/t{char}	;	,
Scan line for previous character	F{char}/T{char}	;	,
Scan document for next match	/pattern`<CR>`	n	N
Scan document for previous match	?pattern`<CR>`	n	N
Perform substitution	:s/target/replacement	&	u
Execute a sequence of changes	qx{changes}q	@x	u

Operator + Motion = Action
When an operator command is invoked in duplicate, it acts upon the current line (e.g. dd)

If we make a mistake while composing text in Insert mode, we can fix it immediately

Keystrokes	Effect
`<C-h>`	Delete back one character(backspace)
`<C-w>`	Delete back one word
`<C-u>`	Delete back to start of line

The keystrokes above can also be used in bash shell

<C-o> Switch to Insert Normal mode

<C-r>0: Paste the text that we just yanked at the current cursor position

R: Enter replace mode

range
- :{start, end}: from line "start" to line "end"
- .: current line
- %: all lines

@:: Repeat the last Ex command

<C-d>: Reveal a list of possible completions

<C-r><C-w>: Get the word under cursor in Ex mode

This chapter is extremely practical

Command	Effect
`[count]G`	Jump to line number
`//pattern<CR>/?pattern<CR>/n/N`	Jump to next/previous occurrence of pattern
`%`	Jump to matching parenthesis
`(`/`)`	Jump to start of previous/next sentence
`{`/`}`	Jump to start of previous/next paragraph
`H`/`M`/`L`	Jump to top/middle/bottom of screen
`gf`	Jump to file name under the cursor
`<C-]>`	Jump to definition of keyword under the cursor
`/`	Jump to a mark

Put \V before words when searching can cancel regular expression

Use <C-r> <C-w> to autocomplete when searching
