In Vim, undoing and redoing operations are simple tasks. The ‘u’ command is used to undo the last operation. For instance, if you delete a line using ‘dd’, pressing ‘u’ will restore it. To undo multiple changes, press ‘u’ repeatedly.
Redoing an undone operation uses the ‘ctrl-r’ command. If you’ve undone a deletion with ‘u’, pressing ‘ctrl-r’ will re-delete it. Like undo, you can redo multiple times by repeating the command.
For more complex scenarios, Vim provides numbered undos. By typing ‘u1’, you’ll undo the first change made in your current session. Similarly, ‘u2’ undoes the second change, and so on. Redoing these actions follows the same pattern but with ‘ctrl-r’ instead of ‘u’.
Vim also offers branching undo trees for navigating through different states of text editing. This feature allows users to move back and forth between various edits without losing any work.
