VBA to copy and paste cells to scattered cells on another sheet

[ATTACH]n1202926[/ATTACH] I was sent this workbook. When the macro is run the cells on "Sheet1" are copied and pasted to various cells on sheet "Letter". Sheet "Map" has a table that specifies the from and to for each cell. It works great BUT, I can't understand HOW! The code identifies the From and To sheets, but I see no reference whatsoever to the sheet "Map" or it's table. Is something missing here, or I just don't understand what's going on? The code:

Sub CopyStuff()
Dim shF As Worksheet        ' From Sheet
Dim shT As Worksheet        ' To Sheet
Dim cl As Range             ' Cell Pointer


' Initalize variables
Set shF = Sheets("Sheet1")
Set shT = Sheets("Letter")


' Copy from range to range
For Each cl In Range("From_Sheet")
    shF.Range(cl.Value).Copy shT.Range(cl.Offset(0, 1).Value)
Next cl
End Sub

Ah Ha! very sneaky and unique way of doing things. Thankyou kindly for solving this mind game Robert. Now that I know, I can put it to good use.
