Can a circle be filled with a triangle fan?

Question

When a cylinder is added to a scene Triangle Fan fill type for the cap is provided in the last operator panel.

Is there any tool to use with a circle to fill it like triangle fan would do?

The alternatives Grid Fill and F (n-gon) can't be used when the vertex in the center of the circle is required.

When you create it, you can go to the Operator panel, and select Triangle Fan for the fill type — someonewithpc, Aug 17 '14 at 12:15

Create and poke face

You can do this with 2 operations.

F, ⎇ AltP

See: Mesh -> Face menu for both.

Note for Blender 2.80 users: Shortcut for Poke Faces was removed and the menu entry relocated to Face -> Poke Faces.

E, Escape, ⎇ AltM, A

Note:

Create face & Poke will assign UV's & vertex colors from surrounding faces (the extrude method will simply extend UV's/colors, which may not be what you want).
Poke uses a more advanced method to calculate the face center point
(noticeable when edges aren't evenly spaced).
