Disable web shortcuts when publishing in HTML5

Hi, I'm fairly new to storyline and I'm dealing with old files (and the new ones I've began to make). I encounter a problematic with some files that were tutorials for a specific software teaching about its keyboard shortcuts. 
The problem is that some shortcuts are using F4, F5 and other keys that once published, trigger the browser's shortcuts. (F5 is especially annoying, refreshing the page).
I've tried searching the forums but didn't find answers there.
Some of the already published projects work fine though, by disabling the shortcuts once the page is opened, so I know it's possible at least.
I thought about disabling the shortcuts via some code but I'm still learning web coding and can't quite find a solution this way.
If there is either a way to disable them via storyline or a fairly simple method around it I would gladly take it.
