How to make smooth switching between marks on Yandex map?

Question

Yandex

It is necessary to make a map with two labels and with their switching by two buttons. It seems to fit, but here it does not work out correctly to specify the coordinates and the controls are not displayed. For me, the Maps API is still like a dark forest.
Please suggest a solution. Just a card with two labels is done easily, plugging in the switch.

Answer 1

Hang on the button event

map.panTo(new YMaps.GeoPoint(30.7058,46.466444), {flying: 1});
