To identify and label a marker that is unlabeled:

1. In the **3D Scene** view, select the unlabeled marker. Scrub back and forward to identify where it is correctly labeled. This is the point at which it is correctly colored in the **3D Scene** view and the **Labeling** panel marker list. You can also observe this on the **Graph**.
2. To label a marker using the tools in the **Labeling** panel, do one of the following, depending on your chosen **Mode**:  
If you prefer to label using **Label** mode:
  1. In the **Manual Labeling Options** section, in the **Mode** line, select **Label**.
  2. In the marker list in the **Labeling** panel, select the name of the marker and then in the **3D Scene** view, select the marker that is currently unlabeled.
  Or, if you prefer to label by dragging, using **Select** mode:
  1. In the **Manual Labeling Options** section, in the **Mode** line, ensure **Select** mode is selected.
  2. In the **Labeling** panel, select the required marker in the **3D** view.
  3. SHIFT+CTRL then click+drag from the selected marker in the **Labeling** panel to the unlabeled marker in the **3D Scene** view.
3. As before, to check the labeling, scrub back and forward in the **3D Scene** view and check that the marker is now behaving correctly.

After you have corrected any swaps, you may want to use Shogun Post's diagnostic tools to help to identify gaps (see [Identify gaps using the Marker Editing panel](https://vicon-help.atlassian.net/wiki/spaces/ShogunPost121/pages/1253738715) and [Review data quality](https://vicon-help.atlassian.net/wiki/spaces/ShogunPost121/pages/1253736541)).
