Navigate Inside Files with Motions

This post extracts some knowledge from Practical Vim Chapter 8 -- Navigate Inside Files with Motions.

[!TIP] Distinguish Between Real Lines and Display Lines

Command	Move Cursor
j	Down one real line
gj	Down one display line
k	Up one real line
gk	Up one display line
0	To first character of real line
g0	To first character of display line
^	To first nonblank character of real line
g^	To first nonblank character of display line
$	To end of real line
g$	To end of display line

[!TIP] Move Word-Wise

Command	Move Cursor
w	Forward to start of next word
b	Backward to start of current/previous word
e	Forward to end of current/next word
ge	Backward to end of previous word

W B E gE for WORDS.

A word consists of a sequence of letters, digits, and underscores, or as a sequence of other nonblank characters separated with whitespace.

The definition of a WORD is simpler: it consists of a sequence of nonblank characters separated with whitespace.

Use WORD-wise motions if you want to move faster, and use word-wise motions if you want a more fine-grained traversal.

[!TIP] Find by Character

Command	Effect
f{char}	Forward to the next occurrence of {char}
F{char}	Backward to the previous occurrence of {char}
t{char}	Forward to the character before the next occurrence of {char}
T{char}	Backward to the character after the previous occurrence of {char}
;	Repeat the last character-search command
,	Reverse the last character-search command

use f and F in Normal mode, and t and T in Operator-Pending mode.

[!TIP] Search to Navigate

/pattern<CR>

[!TIP] Trace Your Selection with Precision Text Objects

Text Object	Selection	Text Object	Selection
a) or ab	A pair of (parentheses)	i) or ib	Inside of (parentheses)
a} or aB	A pair of {braces}	i} or iB	Inside of {braces}
a]	A pair of [brackets]	i]	Inside of [brackets]
a>	A pair of <angle brackets>	i>	Inside of <angle brackets>
a'	A pair of 'single quotes'	i'	Inside of 'single quotes'
a"	A pair of "double quotes"	i"	Inside of "double quotes"
a`	A pair of `backticks`	i`	Inside of `backticks`
at	A pair of <xml>tags</xml>	it	Inside of <xml>tags</xml>

[!TIP] Delete Around, or Change Inside

很多内置插件都采用 package 机制管理，matchit 通常被放在 opt 目录下，因此默认不会自动加载，需要手动：

vim  | Keystrokes | Current content | Keystrokes | Current content | |------------|-----------------|------------|-----------------| | iw | word | aw | word plus space(s) | | iW | WORD | aW | WORD plus space(s) | | is | sentence | as | sentence plus space(s) | | ip | paragraph | ap | paragraph plus blank line(s) |

As a general rule, we could say that the d{motion} command tends to work well with aw, as, and ap, whereas the c{motion} command works better with iw and similar.

[!TIP] Mark Your Palce and Snap Back to It

The m{a-zA-Z} command marks the current cursor location with the designated letter.

'{mark} moves to the line where a mark was set, positioning the cursor on the first non-whitespace cahracter.

`{mark} command moves the cursor to the exact position where a mark was set, restoring the line and the column at once.

Automatic Marks as follows: | Keystrokes | Buffer Contents | |------------|-----------------| | `` | Position before the last jump within current file | | . `` | Location of last change | | ``^ | Location of last insertion | | [ `` | Start of last change or yank | | ``] | End of last change or yank | | < `` | Start of last visual selection | | ``> `` | End of last visual selection |
