• Now we know that by defaultxDelete character

  • Can be inxFront use[count]Double

    • as 10x
    • Deleted characters are stored in""Register
    • Can use:regView register status

Sports help

• We can checkmotionMy documents!!!
• h motion
• motionCursor movement

• Like usGJust go straight to the last line of the document

  • dGIs to delete from the current position of the cursor to the last line. It’s great!

• ggIt’s the first line

  • dggIt is deleted from the cursor position to the beginning!!!
• ggdGIs to delete from beginning to end

• 8GIt’s line 8

  • d8GIt is deleted from the cursor position to line 8
  • What if there are only four lines in total?
  • If there are four lines in total,8GIt’s the last line of the road
  • So, at this timed8GWhat is it, you know?
• Give it a try

Up, down, left and right

• How does the cursor movehjkl
• These aremotion

• If the front isd

• such asdj

  • D stands for deletion
  • J move to next line
  • DJ represents deletion from the current cursor line to the next line
  • Delete two lines in total

• such asdl

  • Delete current cursor character
  • that isx

• such asdh

  • Deletes the character in front of the current cursor
  • Backspace
  • that isX

Doubling factor

• Ifd8j

  • dIs to delete
  • 8jFrom the current cursor position to the bottom8that ‘s ok
  • d8jDeleted everywhere
• aliked7k
• dYes delete
• 7kIt’s seven lines up
• 8 lines in total together with the current line
• It’s all deleted from this scope

• Think about it

  • d8h、d4lWhat are they?

Delete by word

• wbeRemember what that means?

  • If you don’t remember, justh w

• If the cursor is at the beginning of the word

  • wIt’s to the next onewordBeginning of
  • bIt’s the last onewordBeginning of
  • eYes to the currentwordThe end of

practice

• So we know

  • dwDelete from current location to nextwordThe beginning of (including the middle space is deleted)
  • d3wYes, delete from the current location to the next 3wordBeginning of
  • 3dwIs done from the current location3seconddw
  • 3d2wYesd2wdo3second
  • deDelete from current location to current locationwordEnd of (no spaces removed)
  • d4eYes, delete from the current location to the next 4wordEnd of (including current word)
  • dbIs to delete the previousword
  • d2bIt’s the front2Word
• The above is the current cursor at the beginning of the word
• If the current cursor is in a word?

Cursor in word

• If the cursor is in the word

  • wIt’s to the next onewordBeginning of
  • bYes to the currentwordBeginning of
  • eYes to the currentwordThe end of

• Delete it wherever you move it!
• B is to retain the current cursor character and delete it forward
• You have to pay attention to thiswordandWORDDifferences between

Big words and small words

• Definition of big and small words

  • wordInclude spaces and various punctuation as separators
  • WORDOnly spaces are recognized as delimiters

  • such astext-indent

    • namely3 words

  • dWYou can delete this directly. This is very convenient, especially when there are many underscores in the identifier
• It’s no use talking about the sky. You have to practice this!

Beginning and end of line

• Wardrobe

  • ^Is the first non empty character to the line
  • 0Is the first character of the line, whether it is a space or not

• End of line

  • $Skip to the last character of the line, even if it is a space
  • g_Is the last non empty character to the line
  • Press the two keys in turn
  • If you forget, you have to:hCheck it out

• Delete?

  • d^It is to delete the first non empty character on the line and keep the current character
  • d0That is, delete the first character of the line from the current position (whether it is a space or not), and the current character is still retained

  • d2^namelydreach2^anddreach^, in fact, the same, or delete a line
  • d $Delete from the cursor to the end of the line, including the current character where the cursor is located
• d $There is another wayD

Delete to end of line

• :h D

• DItself isd $
• The positioning method also includes in-line search

In line lookup

• adoptfoJust jump to the rightocharacter

• dfoFrom the current positiondreachfoLocation of

  • foThe position of is forward from the current positionfThe second day of arrival1individualoLocation of
  • The current character of the cursor is also deleted

• d2foFrom the current positiondreach2foLocation of

• 2dfoIs todfoimplement2Times

  • dfoFrom the current positiondreachfoLocation of
  • foThe position of is forward from the current positionfThe second day of arrival1individualoLocation of
• The two results are actually the same

Reverse lookup

• Reverse lookup isF

• dFoDelete from current location toFoLocation of

  • FoThe location of is found in reverse from the current locationFThe first1individualoLocation of
  • The character of the current cursor is reserved

• dF2oThe location of is deleted from the current location toF2oLocation of

Coordination repetition

• . you can repeat the last operation
• DF >
• . is to execute DF > again
• Can be inoeasy.javaPractice inside

Intra line attachment

• exceptfBesides, we havet

• f eIs to move the cursor toeabove

  • Yes, jump to

• t eIs to move the cursor toeAbove previous characters

  • It’s close to

• dt(Delete from current location tot(

  • t(It means close to(
