A hover-over of your Worksheet Scroll arrows reveals two more very useful tips!
Ctrl + Left Click on the right arrow shoots to the last sheet. (Ctrl + Left click on the the left arrow will shoot back to the First one.)
Right Clicking on either arrow gives you a Pop-up Contents Page of all your Sheets that is sooo much easier to navigate. Simply Double-click on the Sheet Name once you've found it to take you straight there!
