First, from Jamaica by Chance

The shaddock grew by chance, it seems, from two Jamaican citrus trees in, perhaps, the 17th century. The tree’s fruit was later also known as a pomelo and now, from its taste or how it grows in clusters, as a grapefruit.

Now, speaking of trees, branches, changes and fruits—this time those of your typing labor: Vim has trees to explore!

Jump Back in Time with Vim Undo Branches

When you undo actions, and then make changes from that starting point, what you had originally done and then undone is not lost. Like a versioning system, Vim keeps track of changes in branches. You can restore to any of these branches and undo later changes (as well as having undone the original action).

See Vim Restore Points

To view points to which you can restore the state of a file in Vim:

1. Press : In normal mode for Vim command mode.
2. Type undolist.
   Type less: You can also abbreviate the command to undol.
3. Press Enter.
   

Vim will show a table that lets you identify changes and points to which you can restore the file.

number	identifies the restore point
changes	counts the changes to the text
when	a date and time, relative if recent
saved	the restore point was written to the disk

Jump to a Restore Point

To jump back to a specific state with Vim undo branches:

1. Enter command mode with :.
2. Type u followed by the number of the restore point.
   Restore points: See above for identifying restore points in Vim
   Example: The command can look like :u 12 to jump to right after change number 12.
   Normal mode jumping: You can also press G - in normal mode to jump back one change from the undo list.
3. Press Enter.

To go back in time in Vim:

1. Type : for command mode.
2. Enter earlier followed by relative time.
   What is time: You can give time as s (seconds), m (minutes), h (hours) and d (days) ago.
   Example: :earlier 5h will jump back 5 hours.
3. Press Enter.

Redo in Vim

How to Undo in Vim: FAQ

Can I undo in Vim insert mode while typing?

Yes, though undoing might not do exactly what you expect it to do. The command will still undo one action, that is most typically undoing all input since you entered insert mode.

To undo from insert mode in Vim:

1. Press Ctrl O in insert mode.
2. Now press U.

Can Vim undo changes after I have saved (or reopened) a file?

Yes.

Vim can keep a record of actions for undoing in a file separate from the edited file across sessions.

To enable this kind of persistent undo information in Vim:

• Add set undefile to your .vimrc file.

By default, Vim keeps these files in the same directory as the original file under the same file name with .un~ appended.

You can collect all undo files in a hidden directory instead. To do so:

• Add set undodir=~/.vim/undodir (or any other directory, of course) to. your .vimrc file.
