Part 5/7:
For those who need to paste only the values from copied cells, the Ctrl + Shift + V shortcut serves that purpose without carrying over any formatting.
Adding dynamic data such as the current date or time into cells can be done with Ctrl + ; for today's date and Ctrl + Shift + ; for the current timestamp.
Navigating and Creating New Sheets
Navigational shortcuts such as Alt + Down Arrow move to the next sheet and Alt + Up Arrow return to the previous one in the active workbook. To quickly insert a new blank sheet, simply use Shift + F11.
