The keyboard is an essential component of a PC as I am using the keyboard for writing, specifically known as typing, this content. There are approximately 104 different push buttons or keys on a keyboard. If I ask, 'Do you know the use of all those buttons?' You will probably say 'No' except in peculiar cases if you are a keyboard master. You have seen functional keys on the top row of the keyboards mostly. You have used some of them many times, or there are some function keys whose purpose is unknown to you. The function keys do different tasks in different applications or software. Function keys are also known as F keys. In this article, I am going to discuss the working of all those function keys from F1 to F12 in Windows.
F1:
It is for help. Help in the sense that when your PC connects to an internet connection, you open any program, like, for example, MS Word and press F1, then it will automatically take you to the pages related to MS Word help. The same is the case with browsers.
F2:
If you have named a file, but now you want to change its name (rename). The F2 key is resourceful in that situation. Select the file or folder and press F2. Its name-changing option will be shown, and you will rename it according to your choice. In some cases, pressing F2 will take you to BIOS (basic input/output system) settings if used immediately after switching on your computer.
F3:
F3 is employed to open the search feature of a program. While working on MS Word, press the F3 and the shift keys at the same time, it will change the selected text from lowercase to uppercase letters and vice versa.
F4:
When used together with the Alt key, as Alt+F4, it closes the opened file, folder, or program. It helps you to Go to the desktop screen. It is the same as when you click the red cross to close an application. The combination Alt + F4 + Enter is used to power off your PC.
F5:
F5 is used to refresh the system of the ongoing Windows. It is also helpful in refreshing the contents of a folder. When it is pressed with some other keys like the Shift or the Ctrl keys (Shift+ F5 OR Ctrl + F5) in a web browser, it reloads the opened web page.
F6:
It is used for selecting programs from the taskbar. When used in association with some other keys, such as Ctrl+ Shift+ F6, while working on MS Word, it opens a new document.
F7:
It is used for checking spelling and grammar. It activates thesaurus in Microsoft applications such as MS Office, Outlook, etc. Select all the data and press F7, it will show various options. If you have opened Adobe Photoshop, then pressing F7 will open the Layers menu.
F8:
If you work on an Excel spreadsheet, most often then you must be aware of its use. Open an Excel sheet and press the navigation keys to scroll all the cells then, press F8 to lock the desired cell.
F9:
It is used in Microsoft Office to refresh the document on which you are working.
F10:
Hit F10+ Shift and it will act as the right key in the mouse. Pressing the F10 key alone will open the menu bar in Microsoft applications.
F11:
This key is processed to switch between full-screen mode off and on in various modern browsers.
F12:
This key has a lot of functions while working on Microsoft Office. It is used to save an important file or folder. Pressing Ctrl + Shift+ F12 simultaneously, helps you in printing a document.
Many laptops have a particular function key shown with the Fn button. When Fn is used with the above-mentioned function keys, it does various other tasks. Such as Fn + F1, F2 or F3 will help you control volume. Fn + F5 F6 or F7 will let you control the playing media as rewind, pause, forward, etc.
