Switching on (switching off) of «take vertex» mode («K»)

If the mode is made active, in case at moving the cursor, in area of capture (limited by a rectangle with the center in an edited vertex) there is an existing vertex of any object already existing on a map, the cursor "will be pulled" to it.

At use of a mode it is recommended to switch a map image in the main menu of GIS into a mode: Normal with nodes.
