Commands panel

Transform: Transform selected faces/vertices. If nothing is, the selected entire mesh will be transformed.
Snap: Snap retopo mesh vertices to the surface. It helps if you have changed the object’s state in the scene and want to re-snap retopo mesh. Only selected vertices will be affected if you are in the “Select” tool in vertex mode.
Scale: Scale selected or entire mesh. Each connective cluster will be transformed separately.
Relax: Relax the entire retopo mesh or subset. If you are in the “Select” tool in vertex mode, only selected vertices will be affected.
Import: Import retopo mesh.
Export: Export poly mesh.
Subdivide .
Smooth (CC): Subdivide and smooth the current group with the Catmull-Clark subdivision.
Delete Mesh .
Symmetry: Apply symmetry to the mesh.
Unwarp: Fit all islands onto the UV map.
Store Selection .
Load Selection .
Clear Selection .
Save Contour: This command allows you to save contour in real scale as EPS or DXF for further laser cutting. The length of lines corresponds to the geometrical length. It is helpful if you want to cut shapes using a laser cutter and glue parts together.

Selected

Expand: Expand the area of selected elements.
Contract: Contract the area of selected elements.
Transform: Transform selected faces/vertices. If nothing is selected, the entire mesh will be transformed.
Normal Extrude: Extrude along the average normal direction. Remember that new vertices will not be snapped automatically, but they will snap in further operations if you don’t turn off Auto snap.
Extrude Faces: Extrude faces so that each face will be moved at the same distance whenever possible. Pay attention that in some cases, exactly parallel faces displacement is impossible, but 3DCoat tries to displace as exactly as possible.
Extrude Vertices: Extrude faces so each vertex will be displaced at the same distance.
Intrude: Intrude selected faces.
Shell: Make a shell of selected faces. Fluffy said: First, select the faces you want to “solidify”, then activate the Shell tool…

then use the buttons in the Tool Options window or the arrow gizmo to set the amount of extrusion…

Free Extrude: Extrude in any direction. Remember that new vertices will not be snapped automatically, but they will snap in further operations if you don’t turn off Auto snap.
Cut Edges: Cut Edges into equal segments. The user will pre-determine the number of segments along the selected edge(s).
Snap: Snap retopo mesh vertices to the surface. It helps if you have changed the object’s state in the scene and want to re-snap retopo mesh. Only selected vertices will be affected if you are in the “Select” tool in vertex mode.
Scale: Scale selected or entire mesh. Each connective cluster will be transformed separately.
Relax: Relax the entire retopo mesh or subset. Only selected vertices will be affected if you are in the “Select” tool in vertex mode.
Rotate CW: Rotate selected edges clockwise.
Rotate CCW: Rotate selected edges counter-clockwise.
Extrude: Extrude selected edges.
Split: Select several edges, then click Split. Move the mouse over the edges to specify the split position, then click to split. You may trigger this tool and split selected edges by using the INSERT key.
Collapse: Use BKSP to collapse selected edges.
Delete: Use the DELETE key to delete selected edges.
Edge Loop: Press L to select an edge loop. Select two edges on one edge loop to limit the effect.
Edge Ring: Press R to select an edge ring. Select two edges on one edge ring to limit the effect.
Sel.Sharp:  Select sharp edges.
Split Edge: Split the selected Edges.
Bridge: By selecting two edges, you can create a face.
Set Seams: Mark selected edges as seams (in UV Preview Window).
Delete UV Seams: Delete seams over selected edges (in the UV Preview Window).
Mark as Sharp: Mark selected edges as sharp. Normals will be split along that edges.
Clear Sharp: Clear, sharp edges. Normals will not be split.
Store Selection: Store Selection.
Load Selection: LoadSelection.
Clear Selection: Clear Selection.
Align Vertices: Alignment Vertex by Plane. You can see the direction of movement of the vertices. If selected Faces, Alignment can occur by circle (You can edit the center of the circle and the radius), cylinder or sphere.
Alignment by Plane Orthogonal to Normal is implemented.

Entire Mesh

Import: Import retopo mesh.
Export: Export retopo mesh.
Subdivide: Subdivide poly mesh.
Smooth (CC): Subdivide and smooth the current group with the Catmull-Clark subdivision.
Smooth Selection CC: Subdivide and smooth selected faces using the Catmull-Clark algorithm.
Delete Mesh: Delete poly mesh.
Symmetry: Apply symmetry to the mesh.
Unwrap: Fit all islands onto the UV map.
