  • gf - go file - to file under cursor

  • gg - top of file

  • {line}gg - to line

  • G - to end of file

  • % - jump to matching *({[]})

range selection​

  • % to represent entire file

examples:

:2,10d      delete lines 2-10
:25,$d      delete from 25-eof

Editing​

  • u - undo

{operator}{count}{motion}
2dw         delete 2 words

Doubling an operator, operates on whole line: dd - deletes whole line

Bold an operator is till end-of-line: D - deletes till end-of-line

yl yanks a letter,
yaw yanks a word,
yas yanks a sentence
yi( yanks everything within (
ddp  ddP   swap lines

cut and paste​

d or c actually cut. so we can just dd a line then p it where we want it

text objects​

The benefit of these is that they care less about where the cursor is pointed. so they become more reusable with .

{operator}{a|i}{text-object}
  • i - inner
  • a - outer
-identifiers
wword
ssentence
pparagraph
b or (block inside ()
[block inside []
B pr {block inside {}
" or 'quoted text
tfor tag

examples:

daw       delete a word + trailing whitespace
ciw       change inner word
das       delete a sentance
da"       delete something in quotes 
ci"       change text inside quotes
dat       delete a html-tag
cit       change contents of an html-tag

imange we want to delete all this
/this ENTER
daw
THEN n THEN . for each time we find one we want to delete
