The cursor movement operation of VI command in Linux

In a full screen text editor, the movement of the cursor is undoubtedly the most frequently used operation. The user is skilled at using these commands to move the cursor to quickly and accurately reach the desired location for editing.

The cursor movement in VI can be either in command mode or in text input mode, but the method of operation is different.

In text input mode, you can move the cursor directly using the four arrow keys on the keyboard; in command mode, there are many ways to move the cursor. Not only can you use four arrow keys to move the cursor, you can also use H, J, K, l these four keys instead of four arrow keys to move the cursor, so as to avoid the different machines on the different keyboard definitions brought by the contradictions, and the use of skilled hands can not leave the letter keyboard position can complete all operations, thereby improving efficiency.

The following command completes the cursor movement in command line mode:

The h cursor moves to the left, if enters the number n before pressing the H command, then moves the cursor to the left n characters;

L The cursor moves to the right, if the number n is entered before the L command, the cursor is shifted to the right n characters;

The J cursor moves up, and if you enter a number n before pressing the J command, the cursor moves n characters;

K cursor down, if you enter the number n before the K command, the cursor Xia to move n characters;

0 (0) the cursor moves to the beginning of the line;

The $ cursor moves to the end of the line;
