Why have modes?

(# of keys) (# of modes) = More Hotkeys

The only modes you really need to know:

Normal Mode home base / comma

entry

Insert Mode add text to do

Visual Mode select text

A motionis a hotkey for moving the curso

Important motions:

Next !ord / "ack a word

#nd of word

$- first non-whitespace character on line

%- last character on line

Motions


15/41

VerbsA verb, as you learned in grade school, is

action word. Verbs in Vim are how we ch

the document.

Examples:

&elete - (requires a motion argument)

'ank - copy text

(aste - paste text at cursor position


16/41

VerbsA verb, as you learned in grade school, is

action word. Verbs in Vim are how we ch

the document.

Examples:

)hange - delete & enter insemode

*pen new line


17/41

SentencesThe Vimpoweruser uses compound actio

which can be thought of like sentences.

[verb][# of times to repeat][motion

Examples:

dw = ?

y2w = ?


18/41




Examples:

dw = Delete word

y2w = ?


19/41




Examples:

dw = Delete word

y2w = Yank 2 words

Advanced MotionsNow, lets look at more sophisticated way

moving around the document.

+ind[_] - move cursor to next [_] o

,ill[_] - move cursor beforenext [_] on

Examples:

+- = Move cursor to next m on line

&.,/ = Delete until just beforethe seco

following


23/41

Vim LogicThere are a few patterns in hotkeys that are worth n

For verbs, doubling the hotkey applies it to the entir

'' - yank entire row

)) - delete all characters on row and open I

If an action works forwards, capitalize it to do the sa

backwards:

(/ 0 - paste aercursor / paste beforecurso

*/ 1 - open line aercurrent / open line befo

+/ 2 - find letter forwards / find letter backw


24/41

Putting it all togetheHere are some of my most-used compound actions

&& - ?

&% - ?

),3 - ?

)45 - ?

&6 - ?


25/41

Putting it all togetheHere are some of my most-used sentences

&% - delete until end of current line

),3 - ?

),3 - delete all characters on line unt

semicolon, then enter Insert Mode

)45 - delete all characters 4nside

parenthesis, then enter Insert Mode

&6 - delete until end of document


30/41

Copy / PasteAnything you yank, as well as anything you

is automatically copied to a register. Yousee the current contents of the registers

typing

,2(=$;*(2;/01*(23in Normal Mode.

To paste aerthe cursor, hit (in Normal

or hit 0 to paste before the cursor


31/41

Any action, or command that changes the

document, can be undone or redone.

Not insertion of a single letter - everything

between entering and exiting Insert Mod

To undo, hit 7in Normal Mode. To redo, h;


32/41

Vims most bizarre and beautiful hotkey:

To redo again, hit /You can also provide a number argument

Examples:(Last action is .&!), >/ = ?

(Last action is )!, then we typed dog, then returne

Normal Mode), / = ?

Undo / Redo


33/41



Examples:(Last action is .&!), >/ = delete 8 more wo


Normal Mode), / = ?

Undo / Redo


34/41



Examples:(Last action is .&!), >/ = delete 8 more wo


Normal Mode), / = replace next word

dog

Undo / Redo
