我正在尝试绑定鼠标上的键移以将其与键盘输入结合起来（例如：shift+1、shift+2）

我正在使用的键盘设备是 Razer tartarus，他们的软件在 Monterey 上对我来说并不能很好地运行，所以我编写了一个简单的 Objective-C 脚本来重新映射输入并且效果很好，我还可以使用重新映射鼠标上的输入它附带的软件可以发送键移或shift+1，它可以工作。

但是，当我按住鼠标移位并使用键盘发送键时，不再检测到移位。如果我在 tartarus 上按住 shift 并按下鼠标上的按钮，也会发生同样的情况。

但是我发现如果我使用正常的键盘移位并按下鼠标上的一个按钮，它检测到它有移位+按钮。

我不太确定引擎盖下发生了什么，但我真的很想为此提供一个解决方法，因为我真的需要能够在 Tartarus 键盘上的鼠标 + 键上使用 shift。

我用来在 tartarus 上重新映射键的脚本如下：

#import <IOKit/hidsystem/IOHIDEventSystemClient.h>
#import <IOKit/hidsystem/IOHIDServiceClient.h>
#import <IOKit/hid/IOHIDUsageTables.h>

static NSArray *matchingKeys(void)
{
    return @[
        @kIOHIDVendorIDKey,
        @kIOHIDProductIDKey,
        @kIOHIDTransportKey,
        @kIOHIDPrimaryUsageKey,
        @kIOHIDPrimaryUsagePageKey,
        @kIOHIDLocationIDKey,
        @kIOHIDTransportKey,
        @kIOHIDProductKey,
        @kIOHIDManufacturerKey,
        @kIOClassKey
    ];
}

NSDictionary *createServiceInfoDictionary(IOHIDServiceClientRef service)
{
    NSMutableDictionary *serviceInfo = [[NSMutableDictionary  alloc] init];
    if (serviceInfo == NULL)
    {
        return serviceInfo;
    }
    [serviceInfo setValue:(NSNumber *)CFBridgingRelease(IOHIDServiceClientGetRegistryID(service)) forKey: @kIORegistryEntryIDKey];
    for (NSString *key in matchingKeys())
    {
        [serviceInfo setValue:CFBridgingRelease(IOHIDServiceClientCopyProperty(service, (__bridge CFStringRef)key)) forKey:key];
    }
    return serviceInfo;
}
