If you call it Curl-DH, everything gets much easier! ^_^

You have the nearly invaluable Extend in PKL only unless you want to write a lot of AHK code yourself (but that's possible of course). Yes, editing can be a pain.

But you have what you need in my PKL_eD pretty much. It's in my Big Bag.

I'm revamping PKL_eD these days and one of my latest improvements is that you can specify a base layout and an overriding layout. So you could start with one of my files like Colemak-CAW, and just add another layout.ini for Swedish letters only (and changing layout name etc) without messing with the first file.

The original AltGr mappings are a right mess and I'd much recommend using my Colemak[eD] mappings instead. ;-) If you wish to type a lot of Swedish, you can make a variant with ÅåÄäÖö on brackets/ISO_102.

If you still insist on using the old Colemak AltGr mappings, one way is to use the Win MSKLC install of Colemak, and then a VirtualKey layout with PKL to just add Extend.

So, are users supposed to script these things themselves based on what is shown in the threads? Offering a few templates for the ideas presented here would certainly help.

You can import as many scripts as you like into PKL, you just have to compile it yourself. My PKL repo contains everything you need for that, including source and compiler. And the top-level file is really simple so you could likely do it almost without getting your hands dirty.

I don't know if anyone has made AHK scripts equivalent to that shown on the Colemak Multilingual page - possibly not. The thing about AltGr layers is different people have different priorities for that layer, so there isn't a universally agreed standard.

I have some AltGr AHK scripts here, but they are designed for typing common symbols, not so much international characters.

But it's easy enough to change both PKL and AHK, so your best bet is probably to take DreymaR's PKL config, or an AHK file like mine, and just edit it to suit your needs.

How? I would like to use RAltGr and CapsLock as AltGr. I made some experiments in the pkl.ini, layout.ini etc. but without success. I only was able to de-activate the CapsLock -> backspace

Also LShift + RShift = CapsLock would be nice, but much less critical.

But I was not able to remap function keys.

Actually, it would be acceptable to use CapsLock for AltGr... if you already had Extend mapped to something else.

For example, I previously considered using CapsLock for AltGr, as my LeftAlt is already used for Extend. But instead I decided on using CapsLock for windows/super.

But what would be inferior... is not having an Extend key at all!!.
