2.8.7. Changing the boundaries of an existing selection and annotation

By selection

In the timeline viewer, go through these steps:

  1. Click on an annotation unit to select it.

    Select annotation unit

  2. Select the region where you want the modified annotation to be placed.

  3. Right click on the original annotation and select Modify annotation time or press CTRL+ENTER

    Modify annotation time

  4. Now the length of the annotation becomes that of the selection from the second step.

By dragging with the mouse

If you press ALT, the active annotation is indicated in green and becomes adjustable with the mouse:

  • Only the time-alignment of annotations on the following types of tiers can be modified: annotations on independent tiers, and annotations on referring tiers that fall under the Time Subdivision stereotype (but note that in the latter case, the alignment cannot be extended beyond the boundaries of its parent annotation, see Section 2.1).

  • To modify the time alignment of annotations on all other tiers, change the time alignment on the corresponding parent tier (following the steps above). The time alignment on all referring tiers is automatically updated. The annotations on the referring tier that are no longer within the borders of the annotation on the parent tier are discarded. If you want to shift the annotations on a referring tier in the same way as the annotation on the parent, use the methods described in Section 2.8.8.

  • If two annotations are adjacent you can snap them by specifying the maximum close-value in ms.

By entering a new begin and/or end time

The precise begin and end time of an annotation can be entered in the hh:mm:ss:ms format in a window that can be invoked via the Annotation > Modify Annotation Time... menu or the corresponding keyboard shortcut (by default CTRL+SHIFT+M).

By entering a number of milliseconds for shifting

Annotations can be shifted to the left or the right by a number of milliseconds. See Section 2.8.8.

Changing selection boundaries with the shortcut keys

Use the shortcut key CTRL+J and CTRL+U to change the left boundary of a selection to the left and to the right, respectively. To change the right boundary use the shortcut key CTRL+SHIFT+J and CTRL+SHIFT+U.
