Towards the left of the first sheet tab you can view the navigation buttons
(first,next,previous,last). Right click on the buttons will populate the
sheet list. Select from the popup.
to the left of the worksheet, you see two arrows pointing left and two
arrows pointing right. if you right click on any of these arrows (or
in that general area) you will get a pop-up list of all worksheets in
that workbook. you can just click on which one you want.
hope that helps.
