Forward redirects the user to the selected screen.
If you enable "Stop the bot after the forward to the next message from the user" function, you won't be able to switch to the screen until the user writes something to the bot.
You can select the target platforms for the component, it will work for all platforms by default.
If you enable "Do not execute this component (the component will disappear from the bot, but it will remain in the editor)", the component will not work on platforms, but will remain in its place on the screen.
Forward should be installed only at the very end of the screen, since all the components installed below forward will not work due to the fact that the user will switch to another screen before they are executed.
