I'm trying to swap Ctrl and Fn on Catalina without downloading a new app. As suggested in multiple articles, I tried going to System Preferences > Keyboard > keyboard > Modifier Keys.. in hopes to simply swap the function of two keys. However, Fn is missing from the list of modifier keys. Am I missing something here? Do I need to do something else to make Fn key show up there?
EDIT: I'm using Macbook Pro with touch bar.
Did you select the keyboard from the menu at the top? (Edit: it is not shown if there is only one keyboard.)
If you have installed keyboard or HID drivers, try removing them.
You could also try deleting ~/Library/Preferences/ByHost/.GlobalPreferences.*.plist.
Another way to change the modifier keys is to use KeyRemap4MacBook:
<?xml version="1.0"?>
<root>
<!-- <devicevendordef>
<vendorname>KINESIS</vendorname>
<vendorid>0x05f3</vendorid>
</devicevendordef>
<deviceproductdef>
<productname>ADVANTAGE</productname>
<productid>0x0007</productid>
</deviceproductdef> -->
<item>
<name>swap_command_and_control</name>
<identifier>swap_command_and_control</identifier>
<!-- <device_only>DeviceVendor::KINESIS, DeviceProduct::ADVANTAGE</device_only> -->
<autogen>__KeyToKey__ KeyCode::COMMAND_L, KeyCode::CONTROL_L</autogen>
<autogen>__KeyToKey__ KeyCode::COMMAND_R, KeyCode::CONTROL_L</autogen>
<autogen>__KeyToKey__ KeyCode::CONTROL_L, KeyCode::COMMAND_L</autogen>
</item>
</root>
I fixed the issue!
Turns out that on this keyboard, doing fn + f12 actually disables the windows key. This was turned on by default. This is why nothing was working when I would press the windows key. I pressed fn + f12 again and now everything works :| weeks of frustration all due to me not looking at my keyboard layout :(
