You might find 'nmtui' (Network Manager Text User Interface) more helpful if you prefer an ncurses based interface similar to the GUI nm-applet (but it doesn't work for GUI-only configuration extensions for some VPNs, etc.)

'nmcli' is good for basics, eg:

nmcli == connection summary inc. addresses, routes, DNS

nmcli dev wifi == wifi networks found (inc. specs)

nmcli dev wifi rescan

nmcli con == list configured connections

nmcli con up Connection-Name

nmcli con down Connection-Name

most of the above support intelligent tab-completion including of (space containing) connection names.
