I was using byobu on Ubuntu 11.10 Server and I needed to hit a function key in an app, so I hit F9 to bring up the config menu and switched the keybinding set from "f-keys" to "screen-escape-keys". That worked, but now I can't re-enable all the f-keys.
I found a program byobu-config that brings up the menu again, and I can switch back to screen keys from there. This fixes things for new screen processes, but the effect on the current screen session is weird: it disables the Ctrl+a (screen) keys and restores F2-F8, but F9-F12 still don't do anything (they're just passed on to the foreground process).
Generally, the Fn key is not a real key, not a modifier like Option or Shift, but instead is a hardware toggle, that toggles the meaning of the function keys between their function key behaviour and their hardware key behaviour.
Remapping the Fn key can be done with low level tools. Maybe one day Keyboard Maestro will include low level remapping of keys, but it does not currently. Low level key remapping is really below the level that Keyboard Maestro operates.
So you can use hidutil to remap the Fn key to Control, for example, and then use Fn/Control as a hot key modifier, but it would conflict with existing uses of Control, not provide any new space for hot keys (as the Hyper Key effectively does since pressing all the modifiers is rather cumbersome).
The function keys do work, however Shift-F6, Command-F6, etc don't work. These are very important to me because the IntelliJ IDEA IDE has quite a few such keyboard short cuts. Strangely Command-F6 doesn't work but Command-F12 does!
I am using dell inspiron 5000 series laptop. It was very hard to press the f10,f11 keys by pressing the fn key every time while debugging. Can you please give me the solution how can I be able to access directly the function keys without pressing fn key.
So my kitten really loves to walk/lay on my (MacBook Air) key board and recently he pressed some buttons and now my "function" keys (I think) are no longer working normally. For example, I can't change the screen/keyboard brightness or volume using the regular keys. When I hit them they either perform different functions or it makes a sound. How do I change it back to normal?
+1 to this request - it would be excellent to be able to re-map hotkeys to be more similar across applications, e.g. using F1 in VSCode to open the command palette, it would be much less mentally taxing by making this more consistent.
As suggested, brightnessctl is probably the best solution in your case. You can bind F5 and F6 (without pressing FN, to keep it simple) to execute a particular brightnessctl command. According to my actual setup with LXDE + LXDM, using xbindkeys, you should have a /.xbindkeysrc with something like this
regarding the keys: the only thing left would be to lie to the BIOS about the OS - lookup acpi_osi in the wiki.
Since there's a remote but real chance to stall the boot with a "dumb" parameter, you should try those from the GRUB commandline, ie. press "e" and alter ther kernel line.
I recommend BetterTouchTool, a little menu bar app that I have relied on for years.With it, you could either create universal shortcuts with or without modifier keys, or create application-specific shortcuts so the functions are determined by whichever application is frontmost. Because the F-keys are special, if you encounter controversial behavior, check System Preferences > Keyboard > Shortcuts and disable the shortcuts that hinder your own mappings. I haven't overwritten my F-keys so I can't remember if remapping them with BetterTouchTool causes controversy or not, but if it does, see System Preferences. It's easier to keep track of what functions dominate if you can aim to keep all the rules in one place.
Other times when we are consuming content, we would like the setting OFF in order to easily adjust brightness and volume of the computer. In particular volume is troublesome when the option is ON because even though I can reach across 10 white keys on a piano, my hand is still too small to reach a chord of Fn+F11 or Fn+F12 to adjust volume.
the keyboard system settings may allow for assigning functions to keys F1-F12, but I am a noob. I do not know what to type in the command box in order to cause the volume to increase when I press F10, to cause the volume to decrease when I press F9, to cause the WiFi to turn on (or off when the WiFI is already on) when I press F3, etc. That it what I need help with.
Yes, that did work. Thankyou for redirecting my attention as I had misread the first time. So what would be the command for setting the keyboard backlight bright/dim, and lastly the media player functions rewind, play/pause, fastforward?
Thanks
This was very helpful however I dont have xbacklight my computer informs me upon trying to function key my screen brighter. Upon installing it notifies me of a conlict with Kvantum which will be removed. Is this appropriate or can Kvantum adjust the backlight with its own set of commands? how would I set the keys? Or should I uninstall Kvantum and go with xbacklight?
A lot of editors I've used (outside of terminal based ones) typically bind Find/Find Next and Jump to Definition to one of the F keys. For example in VS Code, F3 is for searching and F12 is for finding the definition. But other than that, I don't really use the F-keys.
Quite a lot actually. I'm in IT and if you're on here I can assume you dabble a bit. Ever alt+ f4? Ever need to hard reload a page? Get into Bios? Also, you may still have function keys hidden under an alt FN. I've used an Planck keyboard before and they get a lot of use that way. FN + 1 = F1 etc.
Unlike Windows, most Linux distributions allow you to remap keyboard shortcuts as you wish - I like to use function keys for a bunch of things but if you don't then you can map your shortcuts to whatever you want.
The keys at the top of your PC's keyboard (the ones that say F1, F2, etc.) are called the function keys. These shortcuts let you quickly access different PC features without searching through a bunch of settings or menus. From changing the screen brightness to adjusting the volume, the function keys will help you maneuver through your PC with no hassle.
Note: Using the Fn hot keys requires installing the Samsung Settings app for your device. Samsung Settings is used for most notebooks running Windows 10, while Book Settings is available for Galaxy Book and Galaxy Book 2. Devices that have Windows 8 or 8.1 will need to download Settings from Samsung Update.
