When I try to right-click on the box that's under the 'This hot key', nothing happens. I can't input right click, and I can't seem to find an option for clicking. (I don't want to move the cursor or anything or click in a specific place. Just click.) Another thing I'm trying to do is after the first action, I want it to click again (not in a specific place, just 1 simple click.) but still, can't find an option to just click.
And lastly, how do I create a macro that whenever I press let's say, "M", it'll enable or disable a group of macros? Kind of like a toggle. I was able to disable the group, but I don't know how to re-enable it. I don't want to keep going back to the Maestro tab to re-enable the script when I need it.
I don't think it is possible to remap mouse clicks in KM.
However, you can trigger a macro on mouse buttons using the USB Device Key trigger (KM Wiki). Perhaps that will work for you.
As I said above, you can NOT remap (use as a trigger) either the right-click or left-click of the mouse. You will need to use other buttons on the mouse.
As @JMichaelTX says, you can detect a mouse button press, but you cannot capture it. So you can detect the right mouse button being pressed with a USB Device Key trigger, but you cannot stop it’s normal action. So you’ll probably want to use a different trigger.
