[NTG-context] defining hashtag simulator

Hi all, I want to define a command that simulate hashtag behavior in social networks, In other words, this command should put the hashtag sign at the beginning of it, replace spaces with dashes and also it should be a clickable link and unbreakable world. I mean like this, for example: \myhashtag{hello world} It should be displayed as #hello_world in the final PDF and when clicked it will search for #hello_world throughout the pdf How is this possible?
