 In addition, the measuring tool will snap to the currently selected layer, provided that layer has its snapping tolerance set. (See Section~\ref{snapping_tolerance}). So if you want to measure exactly along a line feature, or around a polygon feature, first set its snapping tolerance, then select the layer. Now, when using the measuring tools, each mouse click (within the tolerance setting) will snap to that layer.

+\item The \tab{CRS} Coordinate Reference System tab enables you to choose the CRS for this project, and to enable on-the-fly reprojection of vector layers when displaying layers from a different CRS.
+\item With the third \tab{Identifiable layers} tab you set (or disable) which layers will respond to the identify tool. (See the Map tools paragraph from the  \ref{subsec:gui_options} section to enable identifying of multiple layers.)

So if you need to edit one layer, and snap its vertices to another layer, then enable snapping only on the \usertext{snap to} layer, then decrease the global snapping tolerance to a smaller value.  Furthermore, snapping will never occur to a layer which is not checked in the snapping options dialog, regardless of the global snapping tolerance. So be sure to mark the checkbox for those layers that you need to snap to.
