General rules

1. all vim commands can have a number prefix
2. all vim operators(e.g. remove/move/copy) will accept a range
3. if x is the normal function, X is its super function

Navigation key (used to move the cursor)

• hjkl
• w -- word head
• b -- back word head
• e -- next word end
• f -- find (; to next one)
• t -- till
• ] -- next paragraph
• [ -- prev paragraph

Selection key

形容词+名词

• ) -- ()
• ] -- []
• } -- {}
• p -- paragraph
• w -- word

• a -- pend a line -- 在后面插入
• i - insert -- 在前面插入

OPERATOR

NOTE: rule 3 applies to operators

rule 4. if x is normal function, xx is super function

operators require a range, it could be either:

1. operator + navigation/selection key
2. selection + operator (equivalent to '<,'>operator)

• g -- goto (35G: goto line 35)
• c -- change
• d -- delete
• y -- copy (use p to paste)
• v -- visual mode

no range operator

those operators don't need range:

• x -- delete current char
• r -- replace current char

demo

By using dw, we take d as verb and w as noun, making a meaningful sentense: "delete a word".

Bulk replacing

• :[%|$start,$end]s/tosearch/toreplace[/g]
• % to search crossing the whole file
• . means current line
• +3 means to the next 3 lines
• / is not the only separator. you could use anything you want (typically #)
• g to replace globally (without % it means global crossing the line)

misc

• u -- undo
• ^r -- redo
• / -- search (n for next search result, N for prev)
