In my experiments, subjects are asked to answer a question by using a text input field coded as shown here.
I noticed that Firefox ( and I don’t know if Chrome does that too) has a keyboard shortcut enabled, that uses the backspace to go back to the previous page. So, it may happen that the while typing their answer, subjects may need to use the backspace to edit it. I would like to avoid the possibility the using the back space may make them go back to the previous webpage instead of deleting the text they just typed.
Is there a way I could disable browser-specific keyboard shortcuts in the script of my experiment?
