Hazel recently bought a new computer that uses Windows 10. She has found that she can no longer use F4 as a method of toggling a cell reference through the absolute/relative settings. Instead, F4 opens a sidebar about projecting to a second monitor. As Hazel only has one monitor, but lots of requirements to set cell references to and from absolute, this is driving her crazy. She would like F4 to work as it traditionally did in Excel.
Testing on a Windows 10 system indicates that the F4 key still cycles through absolute/relative versions of references. There is a caveat, however: You need to make sure that you are in "edit mode" when it comes to using F4 with formulas. In other words, select the cell you want, press F2 to enter edit mode, use the left and right arrow keys to move through the formula, and press F4 whenever you want to cycle a reference through various permutations of absolute and relative notation.
If the F4 key still doesn't work as you expect, then it is a good bet that you are using a laptop computer or a super-duper, multi-function keyboard with your desktop system. On these types of keyboards the function keys typically do special things, such as adjust your volume, adjust screen brightness, etc. To get to the normal operation of a particular function key, look for a key labeled something like FN (short for "function") or F Lock (for "function lock"). Press or hold down that key (it varies from system to system) as you press the F4 key, and it should work as you expect.

Thanks, Allen
Although not personally having experienced that F4 problem it is a great tip and gives an idea how to potentially fix other function keys not operating as expected- I too use a laptop.

Maybe right click on taskbar, and select "Show Touch Keyboard button" - keyboard icon should appear bottom right corner
lots of useful characters and icons
Then see google response to
get function keys from touch display keyboard windows 10
See the 3rd section
Access Function Keys
And maybe float version so you can push it down to just show the Fn key selections
And - as it's google, you may find the "Ask Anything"
helpful to get more detail on the keyboard presentation.
Not checked, but it may be that you can select a different keyboard driver - but be careful about that

Very shocked when my long-trusted F4 was closing my excel book rather than change cell reference. I noticed in your method (F2 then F4), it only works on a single cell, is there a way to mass change a table's cell references? It's a very frustrating update!
Cheers

It is also possible to create a Windows shortcut that opens some program and assign a function key as a shortcut key to run it. In that case this Windows action will take precedence over Excel shortcut. You would have to find which program is run by that function key, figure out which Windows shortcut has that function key assigned to it, and change or disable it.

If your Keyboard has an Fn key that will be the problem as Allen has indicated.
You can in many cases reverse the functionality of the Fn key, so you need it for the Hotkey functions instead of the Function key functions.
Try a Google search using "How to use the function keys without pressing Fn on a ***** computer"
Good Luck!
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
