How do I show or hide numbering of protein region features in Map view?
Click the Show Numbering Button

Click the "Show numbers" button on the side toolbar to show or hide numbering (start/end coordinates) for region features.
Numbering for regions will only be shown if sufficient space is available.
Numbering is not displayed for site or bond features.
It is not possible to "zoom in" for protein sequences in Map view.
Select a Region, Site or Bond to See It's Coordinates

If numbering is not shown due to space constraints, click on a Region, Site or Bond (or the associated label) to select and see the selection coordinates in the Selection bar.
