From Help | Keyboard Shortcuts:

[Ctrl]+[Page Up] goes to Previous sheet in the workbook
[Ctrl]+[Page Down] goes to next sheet
No quick way that I know of to jump to first/last sheet

What is the shortcut to navigate between worksheets in the same book? I know
Control and Tab navigates between open workbooks but how do you navigate in
the same book?

Thank you.
