Add Japanese Key Keybindings

[IBNobody]

Please add the following Japanese keys to your config/web-config.

The 4 Japanese Keys are:

• 0x1C: Convert
• 0x1D: No Conversion
• 0x19: Half-width/Full-width
• 0x15: Katakana/Hiragana

Background:

One trick I would use often with my Elecom mice was to bind the Japanese keys to the buttons, and then use AutoHotkey to trigger off these buttons. Since I had a US keyboard, I never had any conflict.

You can find my old post here...

I can work on this improvement, but it may not be for a few weeks due to vacation.

I'm not sure what the codes you provided are, but they don't seem to be HID usages for those keys.

I don't have access to a Japanese keyboard, but from what I was able to find, these should be the usages for them:

Convert: 0x8a No Conversion: 0x8b Half-width/Full-width: 0x35 (same as tilde key) Katakana/Hiragana: 0x88

You can try importing this JSON config to see if this mapping does what you want:

{
    "version": 3,
    "unmapped_passthrough": true,
    "partial_scroll_timeout": 1000000,
    "interval_override": 0,
    "mappings": [
        {
            "source_usage": "0x00090001",
            "target_usage": "0x0007008a",
            "layer": 0,
            "sticky": false,
            "scaling": 1000
        },
        {
            "source_usage": "0x00090003",
            "target_usage": "0x0007008b",
            "layer": 0,
            "sticky": false,
            "scaling": 1000
        },
        {
            "source_usage": "0x00090002",
            "target_usage": "0x00070088",
            "layer": 0,
            "sticky": false,
            "scaling": 1000
        }
    ]
}

As mentioned, because the "half-width/full-width" key is the same key as tilde in the USB HID protocol, it won't be possible to map to it separately. Maybe you can use the Japanese backslash/underscore key if you need a fourth one (usage for that one should be 0x00070087).

If the above works for you, we can easily add those keys to the web UI.

I'll give it a shot, but again, there might be a delay due to vacation.

Sorry, the codes I provided were the keycodes that the Elecom driver sends when the keys are pressed.

I am using Switch Hitter as a way to detect keystrokes.

11:17.0859  (0x1C, BIOS 0x00) DOWN
11:17.0981  (0x1C, BIOS 0x00) UP -> 123ms
11:19.0286  (0x1D, BIOS 0x00) DOWN
11:19.0393  (0x1D, BIOS 0x00) UP -> 109ms
11:30.0466  (0x19, BIOS 0x00) DOWN
11:30.0601  (0x19, BIOS 0x00) UP -> 136ms
11:32.0269  (0x15, BIOS 0x00) DOWN
11:32.0454  (0x15, BIOS 0x00) UP -> 187ms
11:52.0256 LCtrl (0x11, BIOS 0x1D) DOWN

0x1C: Convert
0x1D: No Conversion
0x19: Half-width/Full-width
0x15: Katakana/Hiragana

I'm at a loss as to why the keystrokes you recommend are different.

These look like Windows-specific virtual keycodes (as listed here: https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes). USB HID is OS-agnostic and uses its own codes (called usages). The spec doesn't have those Japanese-specific keys, but it has keys like "International1" etc. and from what I'm reading that's what Japanese USB keyboards send for those keys.

Japanese keys should now be supported in the latest version. Please test if you're still interested.
