Edge Data
Edges can have several different attributes that affect how certain other tools affect the mesh.
Edge Crease

Hotkey
Shift-E
This edge property, a value between (0.0 to 1.0), is used by the Subdivision Surface Modifier to control the sharpness of the edges in the subdivided mesh. This operator enters an interactive mode (a bit like transform tools), where by moving the mouse (or typing a value with the keyboard) you can set the (average) crease value of selected edges. A negative value will subtract from the actual crease value, if present. To clear the crease edge property, enter a value of -1.
Edge Bevel Weight

Menu
Edge ‣ Edge Bevel Weight Sidebar region ‣ Transform ‣ Edge Bevel Weight
This edge property, a value between (0.0 to 1.0), is used by the Bevel Modifier to control the bevel intensity of the edges. This operator enters an interactive mode (a bit like transform tools), where by moving the mouse (or typing a value with the keyboard) you can set the bevel weight of selected edges. If two or more edges are selected, this operator alters the average weight of the edges.

Vertices also have a bevel weight which can be edited.

The Sharp mark is used by the split normals and the Edge Split modifier, which are part of the smoothing or customized shading techniques. As seams, it is a property of edges, and these operators set or unset it for selected ones.
