Hey there. Do you think this is possible to implement with the recent changes made to karabiner-elements? (They added 'complex-modifications' support)
Do you have time to dig into this? Perhaps I could help by any means?

* docs: https://github.com/tekezo/Karabiner-Ele … ifications
* complex mods repo: https://github.com/pqrs-org/KE-complex_modifications

Or did you find any other solution to this? I miss extend so hard, since I switched to macOS. This is killing my experience :(((

Where can I get this device and how can I use it to get extend working?
EDIT: I have found it on this forum, thanks. But I am using a Macbook Pro. So it would confuse me rather more, because I constantly switch between laptop and my mechanical keyboard at the docking station.

I think I will fiddle around with the new karabiner complex modifications then. Perhaps I can find a solution to this. (Navigation layer only first.)

I have created a modifications file for Karabiner-Elements which implements Extend here. Open

karabiner://karabiner/assets/complex_modifications/import?url=https://gist.githubusercontent.com/39aldo39/72cd3af3e90ce70b5f1257e815ad912a/raw/52475bf5ed4565f5ab21ac889d29db21420decdf/extend.json

in a web browser to import it directly in Karabiner. (It is not allowed to use non-http protocols in links.) It is still needed to set an extend key in the simple modifications tab with 'to key' as 'fn'. It works independent from the layout, which is nice. The modifiers where a bit tricky to implement, since they remove the extend key. But they work by defining them as modifier+extend. Mouse keys aren't supported by Karabiner-Elements though.

I implemented the standard Extend1 layer minus mouse keys and mousewheels. Those keys can be mapped to something different, but Karabiner-Elements still adds features which stopped working with Sierra. So, they will be probably supported after some time. But they can be mapped to something different in the meantime, of course. However, the GUI key is already mapped as CMD (Ctrl has moved to Q) and other CMD combos aren't really needed imo, since the CMD is on a nice position.

This is really cool! Thanks a lot!! I'll try it out when on my mac at work tomorrow. But I see you're using the 'fn' key as the key to make a switch to the extend layer. Is that a personal preference, or is it impossible to use the caps lock as the access to extend?

Edit: I first tried replacing "fn" with "caps_lock", that worked, sort of, but for every key I had to re-press caps_lock, not so practical. But just by adding the additional mapping of caps_lock to fn, I solved it. (combination like shift+option+arrow are now comfortable again)

Ah, modularity is so nice and the lack of it not so nice. ;-)

If modular ergo mods aren't available, I'd suggest not making all possible combinations as that's madness. Maybe just one vanilla and one fully-modded variant? That is, on ISO boards I'd really consider a plain Angle mod a part of the "vanilla" package, personally. And maybe the full CurlAngleWide mod is too much for some? At any rate, we'd need the CurlAngleWide(Slash) for PC105/ISO and CurlAngle(Z)Wide(Quote) for PC104/ANSI boards, so it's a bit of a hassle.

So, all in all that's:
• Unmodded ANSI
• CurlAngle(Z)Wide(') ANSI
• Angle ISO
• CurlAngleWide(/) ISO

That's enough to discourage making more combos I think. ;-)

One slightly annoying thing about the new Curl(DH) mod is that it splits the ZXCV block so Extend should have "Button1" mapped to the D which is now between C (Cut) and V (Paste) (if mouse buttons are available now, that is). But it's no biggie once you get a little used to it!

I have created a file for Karabiner-Elements which implements mouse/scroll wheel movement. I don't know all the mac equivalents for certain commands so I filled in the blanks with whatever I could think of:

- F key row has been left untouched since it already has media keys (escape is caps lock however)
- "Grave Accent" has been mapped to "Eject"
- "Backspace" has been mapped to "Force Quit (command/option/escape)"
- "Close Bracket" has been mapped to "Spotlight Search (command spacebar; adding option to this opens the finder)"
- "Backslash" has been mapped to "Launchpad"
- "Quote" has been mapped to "Mission Control"
- "Slash" has been mapped to "Mac control (this definitely needs a better spot)"

To install: open Spotlight Search, type the following without quotes "~/.config", look for the Karabiner folder, then copy/paste the json file into the Complex Modifications folder.

If you want to edit the mouse/scroll wheel speed: open the json file with Text Edit, then use command/F to find the numbers 1536 for mouse movement (should get 4 hits) and/or 32 for scroll speed (2 hits). These values are the default speeds you'd get from the standard mouse up/scroll up mappings in Simple Modifications. The fast/slow speed options for those commands are double/half the default (i.e., mouse up is |1536| while mouse up fast is |3072|). Simply use find/replace to edit the speeds to your liking (don't add a negative sign to your search; just stick with the absolute value).

I think for Mac a few things need to be moved around but this should be a decent starting point. If you have any suggestions/know various mac equivalents for windows commands let me know.

Thanks alot mate :)
Modified this a bit so that now extend q would be control instead of escape. :)

Karabiner-Elements uses massive JSON config files to accomplish its complex mappings. To implement Extend, it takes 1200+ lines! That makes customizing or even seeing what its doing a tricky endeavor. We're all keyboard layout nerds, right? Customizing should be possible. Especially since some of the Extend choices are... questionable on a Mac (menu and insert, I'm looking at you... some of the mouse movement and the additional modifiers too).

Anyway, I wanted a way to generate my Extend config so that I could easily customize it. So, I have published a Python script that does just that. It lets you easily customize and generate a Karabiner-Elements Extend JSON file. The project is hosted here: https://github.com/mattmc3/colemak-tool … /Karabiner. The script attempts to stick closely to the default Extend as DreymaR defined it originally so that you can make your own customizations instead of taking mine.

The well commented Python script weighs in at about 250 lines of fairly readable code. Here is a sample from the QWFP row definition:

### top row ###
extend.add_key_mapping("q", "esc")
extend.add_mouse_scroll_mapping("w", "y", Direction.UP)  # mouse scroll up
extend.add_key_mapping("f", "[", "left_command")  # browser back in safari is CMD-[
extend.add_key_mapping("p", "]", "left_command")  # browser forward in safari is CMD-]
extend.add_mouse_move_mapping("g", "y", Direction.UP)  # mouse move up
extend.add_key_mapping("j", "page_up")
extend.add_key_mapping("l", "home")
extend.add_key_mapping("u", "up_arrow")
extend.add_key_mapping("y", "end")
extend.add_key_mapping(";", "delete_forward")
extend.add_key_mapping("[", "esc")
extend.add_key_mapping("]", "insert")

If Python or coding is not your thing, the generated JSON file is available for download here. Or, follow the directions on the site README to download and install the config. Let me know if you find any bugs, and if you are a fellow Python dev, feel free to contribute with a PR.

Works on Sierra, High Sierra, and Mojave. Haven't tested anything below that.

Hello,  this is my first post. I'm still doing 25 wpm after three days (I'm still on the  home row, so here I am on Colemak forums typing on a Qwerty ^_^)

This forum is pretty cool and has useful information. Thanks for everyone contributing, especially DreymaR and stevep99.

I made a configurable script that generates the different layouts for Colemak (or anything else) in Mac OS using Karabiner. The main idea was obtained from the user mattmc3 so thanks for this. Right now, it works by concatenating rules on top of each other, for example, this is what I ran to use my current layout which consists of Colemak + Curl + Angle Mod (Z on shift) + Wide Mod on an ANSI keyboard.

python3 karabiner_config_generator.py "Colemak" colemak.yaml colemak-dh.yaml \
colemak-dh-ansi-z-on-b.yaml colemak-dh-ansi-z-on-left-shift.yaml \
colemak-dh-ansi-wide.yaml > colemak.json

and then on Karabiner I have to apply them in the correct order. Karabiner works by "what comes first is prioritized" so the rules defined in Colemak.yaml have to down the bottom. This reliance on rules order might be confusing so another method that I'm currently working on is merging all the rules in the order they were supplied (last is prioritized) as one set of rules.

A sample rule file is:

title: "Colemak Mod DH - Angle-Mod ANSI Z on Left Shift"
mappings:
    "left_shift": z
    z: x
    x: c
    c: d
    v: v
    b: []

I'll release it in a few days once I clean it up a little and I enable Extend and this is why I'm here. I'll be adapting mattmc3 implementation but I have a few questions, in the Extend thread it's said  that

so should the Extend layout be the same regardless of keyboard layout? My second question is regarding Extend layer in itself. How is it supposed to work, say when it's enabled, should it be disabled manually or does it automatically go back to the normal layer, it seems strange but I see it being recommended a lot so I'm eager to try it out.

I’m using a dvorakoid layout, so my Z, X, C and V keys are all over the place. On my own Extend layer [Undo], [Cut], [Copy] and [Paste] are strictly positional (but on the top row rather than the bottom one). That’s not tricky at all. I think that on QWERTY [Copy] is the only one of these functions that is actually mnemonically linked to its letter key. [Cut] and [Paste] already feel positional there and [Undo] seems to be randomly placed.

Does anyone know if this was actually released somewhere during the few days that have passed since? ;)

I have searched for an implementation of the awesome Extend version of Colemak CAW that can work with the current MacOS, but I haven't found much yet. This post/thread here was probably the closest I have found so far. I have the basic layer working thanks to stevep99's and njdoyle's information and files on Github (https://github.com/ColemakMods/mod-dh/tree/master/macOS), but still no Extend...

I'm using the EPKL when on my Windows PC for work, but "at home" I use a Mac, so the missing Extend layer has been bugging me for a while.

Is there any way for me to get the extend layer working on my Mac? Ideally on CapsLock, but if that's not an option, I could live with a workaround.

Thanks in advance, and thank you to those who have made all of this possible (Shai, DreymaR, stevep99, njdoyle, mattmc3,...)
