To make things faster, instead of using your mouse to navigate multiple Microsoft Excel sheets that are in the same document, you can use a shortcut instead. This is what Sally will be doing to copy data from her first worksheet to the fifth.
The shortcut function that Sally needs to use to achieve this is (A) Ctrl and Page Up or Page Down Keys.
I know the first one is A) Bookmark sites and I think the second one is B) Cross-platform capability.
I'm going have to go with with 1.b and 2.d hope this helps and I don't need help right now.
