Like this?

int user_edit(struct tree *tree)
{
    ...
    for (;;)
    {
	...
	fputs("Command? [acdlsq] ");
	fflush(stdout);
	fgetstnl(cmd, sizeof cmd, stdin);
	c = cmd[0];

	switch (c)
	{
	  case 'a':

	    fputs("Key? ", stdout);
	    fflush(stdout);
	    fgetstnl(key, sizeof key, stdin);
	    fputs("Data1? ", stdout);
	    fflush(stdout);
	    fgetstnl(data1, sizeof data1, stdin);
	    err = add_node(tree, key, data1);
	    break:
	    ...
	  case 'l':
	    fputs("Filename? ", stdout);
	    fflush(stdout);
	    fgetstnl(filename, sizeof filename, stdin);
	    err = load_tree(tree, filename);
	    break;
	    ...
	  case 'q':
	    goto done;
	}

	if (err != 0)
	    fprintf(stdout, "Error: your command failed (%d)\n", err);
	...
    }
    ...
}
