Name of a widget in spreadsheet software used to drag formulas to other cells

Question

You can find it in all spreadsheet applications like Microsoft Excel, LibreOffice Calc or Google Docs. In the Help pages of the latter, it is described as:

a small blue box in the lower right corner [of the cell]

Is there any name given to that widget? How do people normally refer to it when talking to other people? For example:

– How do I copy this formula to other cells in the column?

– Just click and drag this [insert name here] downwards.

Answer 1

Microsoft calls it the Fill Handle, as seen here.
