 Replying to [ticket:70574 barracuda156]:
 > Fails for me on 10.6:

 Most likely upstream issues. Like this one:

 'kVK_RightControl'?

 According to
 [https://opensource.apple.com/source/WebCore/WebCore-7605.3.8/platform/mac/PlatformEventFactoryMac.mm.auto.html
 this Apple code] this could be added to fix that:

 {{{#!c
     // This constant was missing before OS X Sierra.
 #ifndef kVK_RightCommand
 #define kVK_RightCommand 0x36
 #endif
 }}}

 However according to [https://github.com/input-leap/input-leap/issues/1195
 this input-leap issue], the current version requires macOS 10.12. The
 simplest thing to do is to mark the port with that requirement. If you or
 anyone wants to convince the developers to re-add support for older
 versions and help them fix their code for that, the port can be updated
 with the new minimum OS version at that time.
