We should provide keybindings to do the following:
- Just perform the expected command without the user having to enter it (in tutorial mode)
- Free roam mode: a mode in which the user can execute any commands and experiment in any way.
- Skip a command without executing it (warning: the rest of the script may have unexpected behavior)
- Show current progress:
command_no / total_commands
Implement an import_script (or by another name) function that allows us to
make scripts that can be run on their own or combined to form a more
comprehensive tutorial.
