Turns out in firefox, they added a feature on their latest browser at least where you can open man or info pages in firefox simply by typing in `man:<page>` or `info:<page>`<p>Try typing `man:ls` for instance. I tried it on chrome as well, but this seems to be a firefox only feature.

So typing this uri would autoopen these man entries in KHelpCenter.
