# not registered as Keyboard response
I'm having a simple problem with the keyboard_response-Item.
I bought two external push buttons for my experiment and they are programmed to be "d" and "#". Therefore these characters are listed in the "allowed responses"-section of the keyboard_response-item. However, the item only registers when I press "d" not "#". I already tried every other possible way of putting "#" there, meaning I wrote it as "HASH" (listed in the available keys), as "hash", I tried as a variable (i.e. defining "response_allowed" as "#" and then using the variable in allowed keys), I tried wrapping it in quotation marks (as well " as '). I bet there is a simple solution to it and I would really appreciate if someone can tell me what to do, as I don't know how to reprogram the response button to another key.
