How to Trigger Two Functions With One Button in Javascript

Is there a way to have mutliple queued functions to happen from one key?

For example, if I press F12, while in a textbox, it will type H-E-L-L-O wait two seconds, and press enter.

Still doesn`t work!

ok, so where do i add the functions i want? say one is to submit a form, and send you to a new page? How to do that?

another way is to put one in script files as a event listener and another on the button as an onclick
