.
the 1st problem with that script : I want to make a custom block.
2nd: this has more text: "any way". it should report true when somebody shift clicks, or normal clicks.
requirements: no js. (library blocks are still fine since the devs will soon allow js in the library blocks)
I also think this could be added as a primitive as you can recreate many/all of the hat blocks in a predicate form but not this one.
