NUMBERS is used to toggle the display of atom numbers on the search fragment.
Example
By default the NUMBERS button is active so that atom numbers on the search fragment are displayed - see below.

The button can be toggled so that if it is selected while surrounded by a red box then the red box disappears and atom numbers on the search fragment also disappear - see Fig.(ii) below.
