Multi-select + Delete isn't working and it's painful

As the title says, trying to select multiple block elements on a clean-up job and Delete isn’t working. Only functions on single-select.

Thanks!

Sorry, I’m missing some context, I think.

Please provide some more details what exactly you are trying to do and where. Please also provide your code.

When I try to click the trash can it single selects and doesn’t delete anything. I’m sorry, I’m just a cleaner and don’t know how to give you my code. I’m working on Safari on OSX if that matters.
