There's a reason it's called Spacemacs, not NeoVim and major features are centered around the SPC leader key. There are certain things you must learn from Emacs if you want to get the benefit of it, such as Emacs packages. To make it easier to learn, there's a popup with keys and commands there. If you press ?, it brings a cheatsheet like interactive window and you can narrow it down by start typing and press `C-z` to open each command description. For example, if you want to know what each command in `SPC f` does, pres `SPC f ?` then press `C-z` on a command and you get a description on upper window.
