Add a Keyboard Shortcut to Firefox Extension

Question

I'm developing a Firefox Extension. I added a new item to the "Tools" Menu to open my extension, but I would like to add a keyboard shortcut to open my extension (something like 'control + alt + x').

Answer 1

I've found it by myself

<keyset id="mainKeyset"> <key id="key_convert" key="x" modifiers="accel alt" oncommand="OpenMyAddOn()"/> </keyset> 

Answer 2

The commands key is a good way to do this these days; for instance to toggle the main extension pop up (known as the browser_action), use the following in manifest.json:

"commands": {
  "_execute_browser_action": {
    "suggested_key": {
      "default": "Ctrl+Shift+Y"
    }
  }
}

This also exposes an entry in the Add-ons Manager -> Manage Extension Shortcuts settings area where the user can re-map the keyboard shortcut.
