Final answer:
In Excel 2016, a small black arrow appears to guide you when you're rearranging worksheets within a workbook using the click and drag method.
Step-by-step explanation:
The symbol that indicates where a worksheet will be placed during the click and drag method of moving a worksheet in Excel 2016 is a small black arrow. When you click on a worksheet tab and start to drag it to a new location, a black arrow appears to show where the worksheet will be inserted once you release the mouse button. If you drag the worksheet between two existing tabs, the black arrow indicates the space where it will land. This method allows you to easily rearrange worksheets within a workbook.
In Excel 2016, when using the click and drag method to move a worksheet, the symbol used to indicate where the worksheet will be placed is a small, gray box with four black arrows. This box appears when you click and hold the left mouse button on the worksheet tab and start dragging it to a new location.
The symbol is known as the Move Handle. It allows you to easily move worksheets within a workbook, rearranging their order or moving them to a different workbook.
For example, if you want to move a worksheet from the first position to the third position within a workbook, you would click and drag the sheet tab to the right of the second worksheet tab until the Move Handle appears in the desired position.
