Key mappings using `Alt` don't work

[daleconboy]

I tried applying some key mappings on a Mac for the Option key via the likes of <A-h> but the mappings aren't taking effect.

Looking at the logs when pressing the key combinations in question, it's reporting that alt = false , but altGr = true.

• Machine: MacBook Pro 16-inch, 2019
• OS: Monterey 12.0.1
• Oni Version: 0.5.9-nightly (0.5.2198)

keybindings.js

[
  {
    "key": "<A-h>",
    "command": "window.moveLeft",
    "when": "normalMode"
  },
  {
    "key": "<A-l>",
    "command": "window.moveRight",
    "when": "normalMode"
  }
]

Oni Log output when pressing Opt-h
