Bug 202601 – [Cocoa] Right Command key should have location DOM_KEY_LOCATION_RIGHT instead of DOM_KEY_LOCATION_STANDARD

• Component: Platform
• Status: RESOLVED FIXED

[Daniel Bates]

This bug is only applicable to Cocoa platforms.

Steps to reproduce:

1. Visit <https://unixpapa.com/js/testkey.html>.
2. Ensure the show attribute values for DOM 3 are enabled.
3. Press the Command key on the right-side of the keyboard.

Then I see:

keydown  keyCode=93  (])   which=93  (])   charCode=0        
         key=Meta char=undefined location=0 repeat=false
keyup    keyCode=93  (])   which=93  (])   charCode=0        
         key=Meta char=undefined location=0 repeat=false

Notice the location attribute is 0 == DOM_KEY_LOCATION_STANDARD

But I should see:

keydown  keyCode=93  (])   which=93  (])   charCode=0        
         key=Meta char=undefined location=1 repeat=false
keyup    keyCode=93  (])   which=93  (])   charCode=0        
         key=Meta char=undefined location=1 repeat=false

The location attribute should be 1 == DOM_KEY_LOCATION_RIGHT

What harm would it cause to compile this on non-Cocoa platforms?

Event.location == DOM_KEY_LOCATION_RIGHT for VK_APPS when I don't know where it is on keyboards for non-Cocoa platforms. I don't have a keyboard with this key, yet.

Longer term, need to audit if it is 100% correct to map right command to VK_APPS. Got to boot up Windows to double check. I think I recall USB HID spec saying it should be mapped to what corresponds to VK_RWIN.

Anyway, I didn't have a Windows setup to test so I patched ^^^ to match VK_APPS. Probably add a FIXME before landing to explain this if you bless this patch.

A FIXME to clarify this sounds reasonable.
