Neo keyboard layout: Some Keys stopped working

• VSCode Version: Code 1.11.0 (9122ec4b1068bd391e41974f46a4b54c1b9c90f9, 2017-04-05T21:13:24.700Z)
• OS Version: Linux x64 4.4.0-72-generic

---

Steps to Reproduce:

1. Install and activate Neo keyboard layout
2. Open any source file in VS code
3. Put cursor somewhere in the file
4. Press M4 key and hold. Press s key (see image)
5. Instead of the cursor moving left, nothing happens

In the previous version of VSCode (1.10.2 8076a19fdcab7e1fc1707952d652f0bb6c6db331) this worked just fine .

I need some time to understand this keyboard layout. I will ping you in the coming days if you’d be kind enough to help me out. It is unlike anything I’ve seen.

Workaround to switch VS Code to dispatch based on key code again. Add the following setting: "keyboard.dispatch": "keyCode" and restart VS Code

I’m new to VS Code and I use the KOY layout (with some adaptions) on Linux (setxkbmap de koy). Same problem as with Neo2: I can type a hyphen by pressing CapsLock+L in the editor. But shortcuts containing CapsLock don’t work (like zooming out with Ctrl+- = Ctrl-CapsLock-L).

The keybindings issues page recommends running <kbd>F1</kbd> > Developer: Inspect key mappings if nothing else helps.

With the standard German layout (setxkbmap de), I get this for the <kbd>L</kbd> key:

	"KeyL": {
		"value": "l",
		"withShift": "L",
		"withAltGr": "ł",
		"withShiftAltGr": "Ł"
	}

With KOY (setxkbmap de koy), I get:

	"KeyL": {
		"value": "n",
		"withShift": "N",
		"withAltGr": "n",
		"withShiftAltGr": "N"
	},

Apparently, VS Code doesn’t get the higher levels of the layout right!

Some additional technical information about this keyboard layout family (neo, adnw, koy, bone):

In the German default layout, <kbd>AltGr</kbd> is mapped to ISO_Level3_Shift (in Linux). In Neo2 (and alike), <kbd>AltGr</kbd> is mapped to ISO_Level5_Shift and <kbd>CapsLock</kbd> is mapped to ISO_Level3_Shift.

So I think, we should see in the output of > Developer: Inspect key mappings either

	"KeyL": {
		"value": "n",
		"withShift": "N",
		"withAltGr": "-",

(because CapsLock replaces AltGr in Neo2 in terms of being the new ISO_Level3_Shift key)

or

	"KeyL": {
		"value": "n",
		"withShift": "N",
		"withAltGr": "6",

(because you get a “6” when you press the physical <kbd>AltGr</kbd> key plus the <kbd>L</kbd> key as you can see in OP’s screenshot).

I hope, this helps you VS Code developers better understanding our problem.

I’m aware that I (and others) are mixing some issues concerning Neo here. But they might be related.
