How can I type a question mark into a block?

How can I type the "?" character into a block?

When I type "Shift + /" for the question mark character (in a paragraph block), it brings up the 'add block' dropdown. How can I disable this functionality or allow user to close the dropdown but still insert the "?" character?

It's also common to enter the "/" character for example in filepaths e.g. "/user/downloads", but I can't seem to enter the "/" character into the paragraph block.
