The 'interaction' that Steve is referring to sounds like he used AutoFilter
where it automatically puts little drop down boxes in the header of a table so
the user can select what criteria to sort  the table on. This can be found in the
menu Data/Filter/AutoFilter.

Dawn's "InputBox" is a VBA method for the Application object that queries the
user for a specific type of data  (string, cell  address, etc.) It's not clear
whether Dawn means "inputbox" in the generic sense (like any text field) or the
one from the Application object (only done via VBA code) which has multiple
arguments (only one required).

Public Sub makeBold()
Dim rng As Range

' Type:=8 refers to a cell/range
Set rng = Application.InputBox("Select a cell/s", Type:=8)
rng.Font.Bold = True
Set rng = Nothing
End Sub
