How to Undo in Vim?
To undo the last action in Vim, you can use the u key. This key will undo the last change that you made to the document.
For example, if you have made multiple changes to the document and want to undo the most recent change, you can press u to undo that change.
You can also use the U key to undo all changes on the current line. This is useful if you have made multiple changes to a single line and want to revert all of those changes at once.
To redo an action that you have undone, you can use the <Ctrl-r> key combination. This will redo the last action that you undid using the u key.
You can also use the :undo command to undo the last change, and the :redo command to redo the last action that you undid.
How to Redo in Vim?
To redo an action that you have undone in Vim, you can use the <Ctrl-r> key combination. This key combination will redo the last action that you undid using the u key.
For example, if you have made multiple changes to the document and have undone some of those changes using the u key, you can use <Ctrl-r> to redo those changes.
You can also use the :redo command to redo the last action that you undid.
Note that in Vim, the undo and redo history is maintained separately for each buffer. This means that if you switch to a different buffer and make changes, those changes will not be undoable or redoable using the u, <Ctrl-r>, or :undo and :redo commands.
