Re: The button I miss and want
is the forward one. I use it all the time on my Win computers, and sorely miss it on my phones. It is such a pain to back up, realize you shouldn't have, and be forced to re-enter all that data again to get back to where you just were...
Android/Chrome: bring up the browser menu, i.e. scroll up if needed to make the address bar visible, press the three vertical dots. The forward button the leftmost icon on that mini toolbar above the textual menu items.
No, you weren't being thick, it isn't done in a particularly discoverable way.
