   vim undo the rollback operation

   Press u in vi to undo an operation

   u Undo the operation of the previous step
   Ctrl+r to restore the operation that was undone in the previous step

   Note:
   If you enter "u" twice and your text is restored, it should be that your Vim is configured in Vi compatibility mode.
   Redo
   If you undo too much, you can type CTRL-R (redo) to undo the previous command. In other words, it revokes a revocation. To see the execution example, type CTRL-R twice. The character A and the space after it appear:
   young intelligent turtle
   has a special version of the undo command: "U" (line undo). The line undo command undoes all
   operations on the previous edit line . Enter these commands twice to cancel the previous "U":
   A very intelligent turtle
   xxxx delete very
   A intelligent turtle
   xxxxxx delete turtle
   A intelligent
   use "U" to restore the line
   A very intelligent turtle
   use "u" to cancel "U"
   A intelligent
   "U" Command to change itself, "u" command to undo the operation, CTRL-R command to redo the operation. This is a bit messy, but don't
   worry, you can switch to any state with "u" and CTRL-R commands.

   Popular text editors usually have forward and backward functions, allowing you to move back and forth between previously viewed locations in the file. In vim, use Ctrl-O to go back and Ctrl-I to go forward.
