It's from the KLC menu, Project -> Properties -> Optional Settings. On a side note, there isn't really a dedicated AltGr modifier but this setting makes RAlt send RAlt+LCtrl instead. So with a layout that hasn't got AltGr you could still get any 4-level mappings by hitting LCtrl+RAlt+<key>. If you want that gone too, you'd have to set all keys in your layout as 2-level ones I guess.

Using EPKL, to press Alt+F4 I instead press Extend+A+4 which can be hit without going far from the home position. That's nice. I also use Ext+T+4 (Ctrl+F4) to close browser tabs.

If you do insist on making your own KLC file, you'll have to fix the Virtual Key codes manually in the file before compiling it in the GUI. The VK codes are in the second column for each key entry. Make sure you get the OEM_# ones right, as they depend on ANSI vs ISO. It affects backspace, slash, tilde and others. Try it out.

Of course you'd love if the maintainers kept more variants. But there's really only one Shai and he doesn't maintain much. It'd be too much to ask I'm afraid. I maintain EPKL which is quite active.

I've made my alternate layout, with no alt-gr mappings, but I'm still having the problem with hotkeys not using the new layout. I'm currently typing in Colemak, but Windows-p (win-r in QWERTY) opens the Run dialog. Other hotkeys also use QWERTY keys, despite my basic typing being all Colemak. I don't know why  this is happening. It only happens in my modified version, not the original.

The option re-appears so long as no keys in the layout have alt-gr mappings assigned. If any do, the option isn't present. I had to remove all the mappings manually, but I finally got the option to show up. It was unchecked, since I'd removed all the mappings that use it.

As to the VK codes, I think I finally get it. Now my only problem is a KLC error saying that one of my codes is mapped twice. It's the mapping for the semicolon to o. KLC tells me that the same key is mapped twice:

"VK_OEM_1 found at scan code 13 and 27"

Scan code 27 in my file is this:

27    Y        5    o    O    -1        // LATIN SMALL LETTER O, LATIN CAPITAL LETTER O,

and scan code 13 is this:

13    OEM_1        5    p    P    -1        // LATIN SMALL LETTER P, LATIN CAPITAL LETTER P,

I'm not sure what happened here, but until I fix this, KLC refuses to build my layout. Any thoughts?

Also, for anyone else interested, this blog post explains the VK problem well. I found it very helpful.

thank you both for your info. i was able to make my own non-altgr colemak layout. i couldn't have done it without information from both of you, as the info from dreymar was originally over my head, but the link you provided, mehgcap, cleared it up for me

i will say for anyone else following this same path, the installation of the mapping was buggy for me throughout. sometimes it would print qwerty instead of qwfpg, sometimes the right alt key would still behave as altgr (i had to start with the default US layout and modify it from there naming it something other than Colemak), and other times the description wouldn't show in the list of keyboard layouts. i don't know exactly what fixed what, but it required reboots, and now it's working as intended

a.k.a Have you tried turning it off and on again?
Classic.
