Among the keys on your keyboard, the F1 to F12 keys are probably not the ones you use most frequently. While they may not be as obsolete or annoying as keys like Scroll Lock or Insert, their enduring existence invites curiosity.
Understanding the background of these function keys offers insight into their design, which stems from historical limitations in computing rather than their relevance today. Despite changes in user interfaces, these keys can still be invaluable if used wisely.
The Origins of Function Keys
In the 1960s and 1970s, computers operated without modern graphical user interfaces (GUIs).Users had to engage with their machines solely through command-line inputs using the keyboard.
Today, keyboard shortcuts allow users to navigate quickly and efficiently, a concept developed in the 1970s by Xerox employees. While modern systems can hide complex functions behind intuitive menus, users of early systems had to memorize various commands, leading to inefficiency.
Thus, the invention of function keys was pivotal. These keys provided a quick way to transmit commands, with each software having its own specific functions for the F keys. This flexibility helped users adapt to various command-line applications more easily.
A Reddit user, Kufat, noted a significant benefit of this design: it reduced the need for multiple key presses to execute commands. Given that older systems would interrupt the mainframe with every keystroke, minimizing inputs increased efficiency.
Why Are There 12 Function Keys?
The presence of twelve function keys can be traced back to the IBM PC, which popularized this layout after its debut in 1981. The original Model F keyboard included ten function keys on the left side, later transitioning to the iconic Model M keyboard, which was more cost-effective.
This widely adopted design deeply influenced keyboard layouts, standardizing the use of 12 function keys atop most modern keyboards.

Function Keys in Today’s Computing
While originally customizable per application, today’s function keys have somewhat standardized roles. Though specific uses may vary, a few functions tend to recur across applications.
For example, in Windows environments, function keys often perform specific tasks. In contrast, Mac keyboards display functions like brightness adjustment, media control, and Spotlight launch directly on the keys, requiring the Fn or Globe key to activate their typical functions.
Full-sized Mac keyboards even feature additional function keys (F13 to F19), enabling full remapping capabilities, allowing users to customize these keys as needed.
F1
The F1 key primarily opens the Help menu in most programs, serving as a valuable resource for users needing assistance. However, users should note that pressing Win + F1 opens Edge with a Bing search for “how to get help in Windows 11, ” so it’s wise to avoid accidental hits.
F2
F2 is particularly useful for renaming files within File Explorer. Simply select a file and press F2, allowing you to type a new name instantly, which streamlines the renaming process significantly. This functionality also extends to Excel and Google Sheets for editing the current cell.
F3
The F3 key serves as a shortcut to open the search feature in various applications, including File Explorer and browsers. After performing a search, pressing F3 moves to the next result in many programs. In the Command Prompt, it recalls the last command entered.
F4
F4 is most effective when used with other keys. In File Explorer, it quickly positions the cursor in the address bar. Additionally, pressing Alt + F4 closes the current window, while Ctrl + F4 closes the active tab.
F5
F5 is a key that many users frequently engage with, refreshing pages in browsers and File Explorer to update content. For a comprehensive refresh that disregards cached data, use Ctrl + F5. F5 also initiates a slideshow in PowerPoint presentations.
F6
In web browsers, pressing F6 effectively places the cursor in the address bar, just like F4 does in File Explorer, allowing for quick navigation and searches.
F7
F7 quickly activates the spell-checking feature within Microsoft Office applications. Furthermore, Shift + F7 opens the thesaurus for highlighted words. In browsers, F7 enables Caret browsing for keyboard navigation, while the Command Prompt uses F7 to display the command history for the session.
F8
F8 is one of the least commonly used function keys. Its main utility lies in Alt + F8, which opens the macro window in Office applications. In older systems, F8 was used to enter Safe Mode during startup, but this is less relevant today due to improved boot speeds.
F9
In the realm of Microsoft Office applications, F9 refreshes a document in Word and manually sends and receives emails in Outlook, alongside recalculating formulas.
F10
F10 activates the menu bar of applications, allowing users to access options like File and Edit. In Chrome, it focuses on the three-dot menu for navigation. An additional function is Shift + F10, which simulates a right-click operation, useful if the mouse is unresponsive.
F11
F11 is widely recognized for toggling full-screen mode in applications, providing an immersive experience while minimizing distractions.
F12
This key is essential in web browsers where it opens the Developer Tools panel, enabling users to investigate webpage elements and network activity. F12 also facilitates access to the Save As dialog in numerous applications, offering a quicker alternative to Ctrl + Shift + S.
Understanding Function Keys: Form Meets Function
The function keys on your keyboard are a product of historical necessity, possessing varying degrees of utility. Despite their diminishing prominence, they still serve distinct purposes, filling in gaps where standard shortcuts may fall short.
If the traditional functions of these keys do not suit your workflow, consider remapping them to customized commands using the Keyboard Manager, part of the often-underappreciated PowerToys suite.
