Split Function

Hi there

One of the lines in my VBA code reads as follows

Dim oRange As Range
Dim oFindInRange As Range
Dim strSplitAddress As String
Dim blnNullRange As Boolean

.//lines of code//
.//lines of code//
.//lines of code//
.//lines of code//

strSplitAddress = Split(oFindInRange.Address, "$")(1)

what does the Split function do especially with does $ and (1) sign means in this scenario.
I have read up on split functions in excel help but i can't find specific reference to $ or (1) anywhere. Can you please advice?
