\nVim supports a tree-like undo history, allowing you to explore different modification paths:
\n– `:earlier 10m`: Revert to the state 10 minutes ago
\n– `:later 5m`: Move forward in time by 5 minutes
\n– `g-`: Move backward in the undo tree
\n– `g+`: Move forward in the undo tree<\/p>\n
\nAdd these lines to your `.vimrc` file to enable persistent undo:
\n“`vim
\nset undodir=~\/.vim\/undodir
\nset undofile
\nset undolevels=1000
\nset undoreload=10000
\n“`<\/p>\n
