This is an Automator app that toggles the "Use all F1, F2, etc. keys as standard function keys" option in macOS System Preferences. A task that is tedious when done often (which programmers tend to do).
All it does is that it executes this AppleScript snippet:
tell application "System Preferences"
reveal anchor "keyboardTab" of pane "com.apple.preference.keyboard"
end tell
tell application "System Events" to tell process "System Preferences"
click checkbox 1 of tab group 1 of window 1
end tell
quit application "System Preferences"Run make install which installs the following files:
/Applications/fn.app— the app containing the script that toggles the setting.~/Library/Services/fn.workflow— a service that allowsfn.appto be invoked with a keyboard shortcut.
(You can run make clean to remove those files again.)
In OS X 10.9 (Mavericks) and later, you also need to:
- Open the
fnapp once either from spotlight or fromApplicationsfolder (it will do nothing but it's needed for the app to appear in the accessibility menu in step 3) - Go to
System Preferences>Security & Privacy>Accessibility>Privacy Click the lock to make changesand tickfn.appunderAllow the apps below to control your computer.
Run the app. The fastest way to do it is from Spotlight:
- Press
⌘ + space(or similar) to open Spotlight. - Type
fn,fn.appshould be the Top Hit. - Hit
Enter.
- Go to
System Preferences>Keyboard>Shortcuts>Services>General(at the end of the list) and assign a new shortcut tofnservice
