I don't want to mess things up so I would really appreciate it if someone can provide a step by step process of what to do that will definitely work so that F2 can be set to a permanent default of renaming the selected item, just like on older machines that allowed that unless changed via Fn lock key. I discovered this on trying to find an answer via google but am lost. I believe it may be possible in BIOS settings but also read some newer laptops dont have BIOS, they have UEFI (?) and also with F2 not functioning like it has done for years then it can make it more difficult to use F2 I believe to get into a BIOS. Is there a way I can set F2 to a default to rename the selected item as has always been the case with Windows XP and 8.1, basically for years.

However, since there is no Fn lock key on this laptop, the F2 key seems defaulted to decreasing the screen brightness (with F3 being the opposite to increase brightness). using mouse or hold on filename, wait and then click again but I am used to using F2 which is quick and simple. I am very used to using the F2 key to rename filenames and also to open up editing cells within Microsoft Excel spreadsheets. In this way, you can easily change your file or folder name without using a mouse. First, Select that Folder or File using arrow keys. I recently bought a new HP Laptop, model number 15-ba065sa 15.6' with Windows 10 pre-installed. The Shortcut key of Rename is ‘ F2 ‘, with help of this you can easily change your folder or file name without using a mouse.
