excel 2007 how do i insert a bookmark?

[diana]

in excel 2007, how do I create/insert a bookmark?

Ive attempted an alternative method by inserting a hyperlink/boookmark. however on this excel spreadsheet on the Insert ribbon, the Hyperlink is greyed out/disabled.
If I press the shortcut keys Ctrl+K, the result is no action?

many thanks

diana
