A practical, well remembered vim command

Command 1: [VYDC] [IA] [Pair_char]

The above command means that the command consists of three parts, each part of which can be any one of the characters inside []

The first section specifies the action type

The second and third sections specify "Scope of action," based on the position of the current cursor, which is very important

(1)

V:visual Select

Y:copy

D:delete

The difference between C:change and delete is that it will delete first and then enter "Insert Mode", which is equivalent to first D and then press I to enter "Insert Mode".

(2)

Pair_char can be pairs of characters, such as {[<] can also use their corresponding right-close version, such as}] and so on

Pair_char special case, can be a W, representing the cursor is the word (separated by a space), when the middle is using I or a, the difference is that the operation result package does not include the word right space

(3)

I:exclude the Pair_char

A:include the Pair_char

The difference between I and a is that the specified "action range" package does not include the pair of characters specified by Pair_char, that is {} or [] or () or "", and so on

Let's take an example:

Suppose there is a text behavior abcd "FGH Ijk <lmn>";

The cursor is at m (underlined)

vi< function: Selected LMN

ya " role: Copy the" FGH Ijk <lmn> "

di " function: Delete fgh Ijk <lmn>

ci< function: Delete lmn and enter "Insert Mode", the cursor is in the middle of <>

Command 2: [VYDC] [TF] [A_char]

(1)

See also the command 1 (1)

(2)

T:till, exclude the character ' A_char '

F:find, include the character ' A_char '

T and F represent from left to right

In addition, you can use uppercase T and F to represent the right to left

(3)

A_char: Represents a character, special case is 0 and $, representing the beginning and end of a line

Command 3: Uppercase and lowercase conversion gU, GU

(1)

[Visual_select_something_by_someway]gu

[Visual_select_something_by_someway]gu

Select a range of content in some way (you can choose from the v instruction in command 1,2) and convert it to uppercase or lowercase

(2)

GU [IA] [Pair_char]

Gu [ia] [Pair_char]

GU [TF] [A_char]

GU [TF] [A_char]

This is done by specifying the GU to be converted to uppercase, and then by specifying "scope of operation" in the latter two sections.

[IA] [Pair_char] See Interpretation of the command 1

Here the middle part uses I or a seems to be no different

[TF] [A_char] See Interpretation of the command 2
