Slight correction: .maskSecondaryFn is 0x800000 (NX_SECONDARYFNMASK / kCGEventFlagMaskSecondaryFn / NSFunctionKeyMask / 8388608). But simulating 0xFF00000003 key press on mouse click still stands as the goal.

I remapped two hardware keys using the IOHIDEventSystemClient API to ones corresponding to the Fn (Globe) and then manually tested their behavior. The 0xFF0100000030 is equivalent to kHIDUsage_AppleVendorKeyboard_Language, part of the AppleVendor Keyboard Page (0xff01) usage page, and the 0xFF00000003 is equivalent to kHIDUsage_AV_TopCase_KeyboardFn, part of the AppleVendor Page Top Case (0x00ff). Reference: Apple’s official HID usage tables

I also tried using IOKit.hid directly, but that didn’t help either. Nor did info available here: https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/EventOverview/HandlingKeyEvents/HandlingKeyEvents.html

I’m talking about inner rim stroke that almost every window, popover, menu, etc. in the system has. This stroke is more apparent in dark mode.

There’s a reason I emphasized “while maintaining the system’s dynamic, contrasting border.” The solution you linked to, like every other one on the web, does not provide a window border that masks to the containing view.

They won’t. The highest voted solution is quite inelegant since it’s hardcoding strings, and my app is localized in numerous languages. I would need to find the menu names for each language and then match the strings. The other, where someone suggested using UIMenuBuilder – that API isn’t available on macOS, and I’m not using Mac Catalyst.

Of course.

You’re a legend. Amazing as always. Thank you.

I just emailed you the details. I think you’ll find it interesting. let myEmail = "rakic" + "@" + "me.com"

Since KBGetLayoutType and LMGetKbdType are Carbon APIs, although not yet deprecated, is it okay to use them for Mac App Store distribution?
