Hi Akash -
Background: I’ve never customized Rhino on macOS before testing only some of that in the Rhino 8 WIP.
That said, I’ve read the question several times - and the updated thread - but have no clue what you are asking. I’ll need lots of details here, I suppose. “Long-cuts” sound like “Aliases” but those are in Rhino 7.
Apart from that, when 3dconnexion is mentioned, I stop reading.
