Tab key for safari documents

I'm using Google Docs live online and can't find the Tab key on my keyboard. There are a few more I can't find either. I've seen the comments so I know you already know which ones I'm talking about. Can we integrate ALL the features of a normal keyboard into my phone's keyboard please? My partner has a pc-based dinosaur that figured this out. Hook a sister up, I got books to write. Hate to have to switch back to PC based phone, but I will if this hiccup isn't fixed.
