Thanks for going through this with me. On the macro I attached on the OP, you can see that I have my Razer Naga mouse button #6 being used as the trigger. The issue is that the trigger works when the button is released which means that despite having two different commands depending on the time, if I hold it down for a second for example upon release it executes the Shit+J command again which is what I'm trying to avoid.
Through your link I downloaded the one shown here Macro Trigger Option Using Long Press of Hot Key [Example]
Where I'm having the issue is the part that says "If any of the following is true: THE KEY is down". I'm supposed to match that key with the trigger up top but given I use my mouse button, there is no option for a USB device Key in that window.
