Manual G-code entry

Can the default Z-axis speed be adjusted? Or can g-code (movements) be entered directly? I’m used to being able to entering things on my 3-D printer to move things around more quickly. Just curious …

From what I have learned the maximum can’t be adjusted in the default configuration. There are two Gcoode macros that can be set, otherwise the directional pad in ground control can be used to position the router and set home.
