I think the default mod key is the ‘super’ key (formerly known as the windows key). It might be alt actually, I don’t remember. Super + 1-9 switches between workspaces, which hold your windows. Shift + super + 1-9 moves a window to another workspace. you can find more key bindings by viewing $XDG_CONFIG_HOME/sway/config (or wherever config files go on your system).
