Switch from Insert mode to command-line mode by pressing the [ESC] key. 3). Move the cursor vi can be directly with the cursor on the keyboard to move up and down, but the normal VI is the lowercase English letter [h], [j], [K], [l], respectively, control the cursor left, bottom, upper, and right to move one grid. Press [CTRL]+[B]: Screen to "back" to move a page. Press [CTRL]+[F]: Screen to "front" to move one page. Press [Ctrl]+[u]: Screen moves to "rear" half page. Press [CTRL]+[D]: Screen to "front" to move half a page. Press [GG]: Move to the first line of the article. (may only work in vim) press [G]: Move to the end of the article.

They are the H, M, and L commands, respectively. (1) The h command moves the cursor to the beginning of the first line of the screen (the upper-left corner), which is the first row of the current screen, not the first line of the entire file. Use this command to quickly move the cursor to the top of the screen. If you precede the H command with the number n, move the cursor to the beginning of the nth row. It is worth mentioning that using the command DH will remove everything from the current line of the cursor to the first line of the screen displayed. (2) The M command moves the cursor to the beginning of the middle row of the screen display file. That is, if the current screen is filled, move to the middle row of the entire screen, or, if not filled, to the middle row of those lines of text. This command allows you to quickly move the cursor from anywhere on the screen to the beginning of the middle row of the screen display file. For example, in the case where the above screen is displayed (regardless of where the cursor is on the screen), in command mode, after entering command m, the cursor will be moved to the letter a of the add line. It is also worth mentioning that using the command DM will delete everything from the current line of the cursor to the middle row of the screen display file. (3) L command when a file displays more than one screen, the command moves the cursor to the beginning of the lowest line on the screen, and moves the cursor to the beginning of the last line of the file when the file displays less than one screen. Visible, this command allows you to quickly and accurately move your cursor to the bottom of the screen or to the last line of the file. If you precede the L command with the number n, move the cursor to the beginning of the nth line from the bottom of the screen. It is also worth mentioning that using the command DLAll content from the current line of the cursor to the bottom row of the screen will be deleted. 4).
