As Suzanne says, it isn't possible (without a field). You could type the
number and then fire the following macro with an keyboard shortcut:

Sub ConvertSelectedRawNumbersInTableToCurrencyFormat()

If Not Selection.Information(wdWithInTable) Then
MsgBox "Place cursor in a table cell or select multiple cells."
Exit Sub
End If

Dim oCl As Word.Cell
Dim oRng As Range
Dim Count As Integer
For Each oCl In Selection.Cells
Set oRng = oCl.Range
oRng.End = oRng.End - 1
With oRng
If IsNumeric(oRng) Then
.Text = FormatCurrency _
(Expression:=.Text, _
NumDigitsAfterDecimal:=2, _
IncludeLeadingDigit:=vbTrue, _
UseParensForNegativeNumbers:=vbTrue)
End If
If IsNumeric(oRng) = False Then
Count = Count + 1
End If
End With
Next oCl
Selection.Collapse wdCollapseEnd
If Count = 1 Then
MsgBox "The selected cell is empty or content is not numerical.", ,
"Notice!!"
End If
If Count 1 Then
MsgBox "" & Count & " of the selected cells are empty or content is not
numerical. Conversion complete on all selected numerical cells.", ,
"Notice!!"
End If
End Sub

How do I get a cell to automatically convert a number to currency
with a decimal point and comma separators? I do not need a formula
in the cell I would just like to type a number, say 5000, and have
it automatically convert to 5,000.00.
