generate custom key code

[glehmann]

Hi!

I’d like to generate custom key codes on macos for the spot light, dictation and do not disturb keys that have to be explicitly dealt with in the kanata configuration.

The community has already identified the codes:

• 0x221 in page 0x0C for spotlight
• 0xCF in page 0x0C for dictation
• 0x9B in page 0x01 for do not disturb

reference: https://www.usb.org/sites/default/files/hut1_4.pdf

Is there a way to define a key to emit those code in my kanata config?

There isn't a way without modifying some code and recompiling yourself.

You would need to add an OsCode mapping in this file:

kanata/parser/src/keys/macos.rs

Line 624 in 1605713

OsCode::KEY_SEARCH => Ok(PageCode {

You can pick an arbitrary unused OsCode if there isn't

And then you would add a name for it:

kanata/parser/src/keys/mod.rs

Line 342 in 1605713

"mwr" | "mousewheelright" => OsCode::MouseWheelRight,

Or otherwise use arbitrary-code or deflocalkeys to name it in the configuration. But probably better to add a name in the code if you're already modifying.

thanks, I’ll give it a try!

It (mostly) works! Apparently I didn’t find the right key code for Do Not Disturb. Is there a way to read the keycode when I press a key on macos?
