# Commits tab in merge requests **(FREE)**
|
|
|
|
The **Commits** tab in a merge request displays a sequential list of commits
|
|
to the Git branch your merge request is based on. From this page, you can review
|
|
full commit messages and copy a commit's SHA when you need to
|
|
[cherry-pick changes](cherry_pick_changes.md).
|
|
|
|
## Merge requests commit navigation
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/18140) in GitLab 13.0.
|
|
|
|
To seamlessly navigate among commits in a merge request:
|
|
|
|
1. Select the **Commits** tab.
|
|
1. Select a commit to open it in the single-commit view.
|
|
1. Navigate through the commits by either:
|
|
|
|
- Selecting **Prev** and **Next** buttons below the tab buttons.
|
|
- Using the <kbd>X</kbd> and <kbd>C</kbd> keyboard shortcuts.

WARNING:
|
|
This feature is in [beta](https://about.gitlab.com/handbook/product/gitlab-the-product/#beta)
|
|
and is [incomplete](https://gitlab.com/groups/gitlab-org/-/epics/1192).
|
|
Previously merged commits can be added, but they can't be removed due to
|
|
[this bug](https://gitlab.com/gitlab-org/gitlab/-/issues/325538).
|
|
|
|
This in-development feature might not be available for your use. There can be
|
|
[risks when enabling features still in development](../../../administration/feature_flags.md#risks-when-enabling-features-still-in-development).
|
|
Refer to this feature's version history for more details.
|
|
|
|
When reviewing a merge request, it helps to have more context about the changes
|
|
made. That includes unchanged lines in unchanged files, and previous commits
|
|
that have already merged that the change is built on.
|
|
|
|
To add previously merged commits to a merge request for more context:
|
|
|
|
1. Go to your merge request.
|
|
1. Select the **Commits** tab.
|
|
1. Scroll to the end of the list of commits, and select **Add previously merged commits**:
|
|
|
|

|
|
|
|
1. Select the commits that you want to add.
|
|
1. Select **Save changes**.
|
|
|
|
To view the changes done on those previously merged commits:
|
|
|
|
1. On your merge request, select the **Changes** tab.
|
|
1. Scroll to **(file-tree)** **Compare** and select **previously merged commits**:

### Enable or disable viewing merge request commits in context **(FREE SELF)**
|
|
|
|
Viewing merge request commits in context is under development and not ready for production use. It is
|
|
deployed behind a feature flag that is **disabled by default**.
|
|
[GitLab administrators with access to the GitLab Rails console](../../../administration/feature_flags.md)
|
|
can enable it.
|
|
|
|
To enable it:
|
|
|
|
```ruby
|
|
Feature.enable(:context_commits)
|
|
```
|
|
|
|
To disable it:
|
|
|
|
```ruby
|
|
Feature.disable(:context_commits)
|
|
```
