CTRL-I is equivalent to pressing a tab key

The CTRL-W is not removing all characters before the cursor, it removes a word before the cursor

The CTRL-P is recall the previous command, the CTRL-N is recall the next command

The CTRL-V enables the next special character to be inserted at the current position, for example, a CTRL-V can insert a character at the current position, where ASCII is 9, otherwise the result is usually followed by a command

The CTRL-C removes the edit of the current command line from another line.

The CTRL-S temporarily freezes the input of the Current Shell

ESC-C: make the first letter of the next word in uppercase, and move the cursor forward to a word. For example, if the cursor stays on a letter of the word, for example, the o letter in the word, the o letter is changed to uppercase.

ESC-u converts all the letters of the next word to uppercase, And the cursor moves forward to a word. Same as above, if the cursor is on the O letter, the Ord is capitalized, and W remains unchanged.

ESC-L is the same as the ESC-U, but make it all lowercase.

I tried all the CTRL keys in bash and summarized them as follows (all the keys listed below are CTRL keys ):

H. delete a character before the cursor

3. A E

A move the cursor to the beginning of the line

E move the cursor to the end of the row

4. F B

F move the cursor one character to the right

B. move the cursor to the left of a character.

5. N P

N next command

Command on P

6. L

L clear screen

7. r

8. t

T Replace the character at the cursor with the character before the cursor

Basic skills:

View command history with up/down keys

Left/right key area modification content

Tab to fill in the command name or directory. The file name is not unique. Press twice to display the list.

! Ls re-runs the last command starting with 'LS'. If LS-L is first followed by LS-lcrt, then! Ls, equivalent to LS-lcrt

Ls abc.txt

Vi! $

VI in the second line! $ Is equivalent to VI abc.txt ,! $ Is equal to the parameter of the previous command. '$' is the last row and column in the context.
