user: Explain Select Menu in complete detail according to the official Blender documentation.

assistant: All `A`
:   Selects all UV elements.

None `Alt`-`A`
:   Deselects all UV elements.

Invert `Ctrl`-`I`
:   Inverts the current selection.

Box Select `Alt`-`B`
:   See [Box Select](../../interface/selecting.xhtml#bpy-ops-select-box).

Box Select Pinned `Ctrl`-`B`
:   Like *Box Select*, but only selects [pinned](../../modeling/meshes/uv/editing.xhtml#bpy-ops-uv-pin) UV vertices.

Circle Select
:   See [Circle Select](../../interface/selecting.xhtml#bpy-ops-select-circle).

Lasso Select
:   See [Lasso Select](../../interface/selecting.xhtml#bpy-ops-select-lasso).

More/Less `Ctrl`-`NumpadPlus`, `Ctrl`-`NumpadMinus`
:   Expands/contracts the selection to/from the adjacent elements.

Select Similar `Shift`-`G`
:   Selects UV elements that are similar to the [active](../../glossary/index.xhtml#term-Active) one in some way.
    The [Adjust Last Operation](../../interface/undo_redo.xhtml#bpy-ops-screen-redo-last) panel provides several options:

    Type
    :   The property to compare. Which properties are available depends on the
        [Selection Mode](#bpy-types-toolsettings-uv-select-mode).

        Vertex Selection Mode
        :   Pinned:
            :   Selects vertices with the same [pinned](../../modeling/meshes/uv/editing.xhtml#bpy-ops-uv-pin) state.

        Edge Selection Mode
        :   Length:
            :   Selects edges with a similar length in the UV map.

            Length 3D:
            :   Selects edges with a similar length in the 3D mesh.

            Pinned:
            :   Selects edges with the same pinned state.

        Face Selection Mode
        :   Area:
            :   Selects faces with a similar area in the UV map.

            Area 3D:
            :   Selects faces with a similar area in the 3D mesh.

            Material:
            :   Selects faces that have the same [Material](../../render/materials/index.xhtml).

            Object:
            :   Selects faces that belong to the same object.
                This is useful when multiple objects are in Edit mode at once.

            Polygon Sides:
            :   Selects faces with a similar number of edges.

            Winding:
            :   Select faces that have the same orientation (facing upwards or downwards in the UV map).

        Island Selection Mode
        :   Area:
            :   Selects islands with a similar area in the UV map.

            Area 3D:
            :   Selects islands with a similar area in the 3D mesh.

            Amount of Faces in Island:
            :   Selects islands with a similar number of faces.

    Compare
    :   The comparison operator.

        Equal:
        :   Select elements whose value is equal.

        Greater:
        :   Select elements whose value is greater or equal.

        Less:
        :   Select elements whose value is less or equal.

    Threshold
    :   Tolerance for values that are almost, but not quite the same. A higher threshold will select more elements.

Select Linked
:   Linked `Ctrl`-`L`
    :   Selects all elements that are connected to the currently selected ones.

    Shortest Path
    :   Selects the path between two selected elements. (See below)

Select Pinned `Shift`-`P`
:   Selects all pinned UVs.

Select Split `Y`
:   “Detaches” the selected faces so they can be moved elsewhere without affecting their neighbors.

Select Overlap
:   Selects all UV faces that overlap each other.
