You can hit F5 to see the Goto dialog.
Then type an address of a cell -- if you include the name of the worksheet,
that'll work, too.
like:
Sheet1!x99
or
'Sheet 99'!z23
If you're looking to select a different worksheet...
If you rightclick on the VCR like controls (to the left of the worksheet tabs),
you'll see a list of worksheets in that workbook.
Other options:
Maybe you could use David McRitchie's Build Table of Contents to get the list
and the hyperlinks all at once:

Another option if you want a more generic solution:
http://contextures.com/xlToolbar01.html
(From Debra Dalgleish's site.)
It builds a toolbar that you can use with any workbook to navigate to any
worksheet. There's a link on that site for an xl2007 version for the ribbon
(from Ron de Bruin).
