right_option not working properly

[szakoba]

Hi there,

This is my first GitHub post, so I don't know how the community works here, but maybe you will be able to help me.

I recently purchased a Keychron K4 and wanted to program some simple modifications to my liking. Everything works fine but for one thing which happens to be the most important for me. I am a Polish language speaker and we have a lot of diacritic letters. I always had both [option] keys on my keyboard, left and right. Right option is not on the keyboard, so I removed the [right_control] cap, because I don't really need it on Mac, replaced it with the [fn] cap and put the [right_option] cap in place of [fn].

So on my keyboard initially the keys on the right side of spacebar looked like this: [command] [fn] [control] And I replaced the keycaps to this order: [command] [option] [fn]

My modifications in Karabiner Elements looks like this: From key ---> To key [fn] ---> [right_option] [right_control] ---> [fn]

And finally here is my issue: the [right_option] key doesn't work properly. It doesn't work with any keyboard shortcuts and produces only some of the diacritic letters: (ą) (ę) (ń) with uppercase, but I'm unable to do (ć) (ł) (ó) (ś) (ż) (ź).

When I check in Karabiner EventViewer it all looks alright, and when I press the new [right_option] it shows as [right_option]. When compared to the Apple Magic Keyboard (which works properly), it produces the exact same events in the Viewer program.

I've found a workaround: instead of modifying [fn] ---> [right_option] I can do [fn] ---> [sticky right_option], but it doesn't satisfy me because it is really tiresome and unnatural in practice.

I would be grateful if anyone would provide me with the solution to my issue. All the best,

Szakoba

could you make a paste bin of your code so I can see it?

[szakoba]

Hey, I don't know what code you are referring to (I'm a computer dummy), so I paste here the only code I could find associated with Karabiner, which is in ~/.config/karabiner/karabiner.json Is it the one? Thanks

[rejnowskimikolaj]

Hey! I have the same issue. Did you guys find anything out?

[szakoba]

Hey, unfortunately not…. Im starting to getting used to using only the left one…

[rejnowskimikolaj]

What a piece of crap

[Wasiollo]

It is also strange that this only happens for the fn mapping to right_option. Mapping, for example, right_command to right_option does not generate such problems.

EDIT: In my case, this is because the keyboard does not send the fn key event to the operating system and handles it internally.

Apologies for updating issue without deep verification.

[kagiura]

Any updates? I've also just resorted to using just the left one, but it's been this way for years and it's kinda getting annoying :,)
