VIM Command Summary

1. Delete characters
To delete a character, simply move the cursor over the character and press "X".

2. Delete a row
Delete a whole line of content using the "dd" command.

After deletion, the following lines are moved up to fill the vacancy.

Suppose you mistakenly delete too much content.

Obviously you can enter it again. But the command "U" is more convenient. It is able to undo the last operation.

5. Redo
Suppose you undo it many times. You can also use ctrl-r (Redo ) to reverse the undo action.

In other words, it is an undo to undo. The Undo command also has a form,the "U" command, which undoes all operations on one line at a time. The second time you use this command, the previous "U" action is undone. with "U" and ctrl-r you can retrieve whatever state of operation.

6. Append (this time back into the edit state, ESC exits the edit state back to the command State)
The "I" command is able to insert text before the current cursor.
The "a" command is able to insert text after the current cursor.
The "o" command is able to start another line below the current line and turn the current mode into insert mode.
The "o" command (note that the uppercase letter O) will be a row above the current line.
