Hello,
The "show" command works well for navigation and menu buttons in most applications. If it is an application you use often, you can improve efficiency by creating a custom mode for the application. Most applications provide keyboard shortcuts for navigating and other actions. You can create custom voice commands that trigger the keyboard shortcuts. You can look at the provided mode files in the config\modes directory for examples of mode files. You can also look at the detailed documentation for customization, starting with YAML:

If you create a command called "go back", you must ensure that the "chrome" mode is not active at the same time as your custom mode, because both modes would have the same command name defined in them.
