The F2 key is a function key found at the top of almost all computer keyboards. The key is most often used in Microsoft Windows to rename a highlighted file or icon. F2 also has many uses depending on the computer and program, as mentioned below.
How to use the F2 key
Open the program that uses the key and press F2. If the F2 key also has an icon on the key, it indicates the key has a secondary function. To use the secondary function, press and hold down the Fn key, and while continuing to hold the key, press F2.
If when pressing the F2 key the secondary function is performed (e.g., mutes audio), the function keys are the secondary function. For example, on an Apple computer, to press F2, hold down the fn key, and press F2.
If the FnLk (function lock) is enabled, the keyboard acts as if the Fn key is being pressed until it is unlocked.
Information about what the secondary function may be is found on the below secondary function of F2 section.

Where is the F2 key used?
The following list is all of the locations the F2 key can be used with information about how it's used.
In Microsoft Windows and Windows program, when an icon, file, or folder is highlighted or selected, pressing F2 renames the file. For example, you could open a folder in Explorer, select a file, and press F2. Once pressed, the file is highlighted, and you can type a new name for the file.
If multiple files are selected when you press F2 to rename a file, all selected files take on the new name. For example, if you had three different named files selected, press F2, and rename a file to "test," all three files use that name and become "test (1)," "test (2)," and "test (3)."
In Microsoft Excel, F2 edits the active cell. For example, you could use the arrow keys to navigate to a cell containing text you want to edit. Once the cell is highlighted, press F2 to edit the cell and then add text or otherwise edit the text in the cell.
