I've found these in the scratch-blocks code: https://github.com/scratchfoundation/scratch-blocks/blob/3374d0cc5aeea90d8a93b05cc563d54416bf441d/src/fields/scratch_field_variable.ts#L117-L147 They can be useful for working aroung the "popups hide instantly on mobile" bug on devices where the long-tap doesn't work, if the dropdown is very high. I've also tried to make the "Rename broadcast" version, but unfortunately Scratch has some code that prevents it from working and makes it log "Unexpected attempt to rename broadcast" instead
