Use this command to extract a change from `HEAD', while leaving

it in the working tree, so that it can later be committed using

a separate commit. A typical workflow would be:

|
0. Optionally make sure that there are no uncommitted changes.
|

|
1. Visit the `HEAD' commit and navigate to the change that should
|
||
|
|
not have been included in that commit.
|
||
|
|
2. Type \"u\" (`magit-unstage') to reverse it in the index.
|
||
|
|
This assumes that `magit-unstage-committed-changes' is non-nil.
|
||
|
|
3. Type \"c e\" to extend `HEAD' with the staged changes,
|
||
|
|
including those that were already staged before.
|
||
|
|
4. Optionally stage the remaining changes using \"s\" or \"S\"
|
||
|

and then type \"c c\" to create a new commit."
