Is anyone else out there having a problem using bat form?

I get to the map to select where I want to go but I cannot figure out what button to use to finalize my selection and get transported to where I want to go.

Same here. I remaped key bindings to C - atack, X - action, Z - magic/missle, F - forms (others as well but, I don't think it matters), and can't choose the location. Enter confirms every choice in menu, and even picking the form, however it doesn't confirm the location once the bat form is selected. And none of the keys I mentioned above does it.

Strangely, the confirmation button in the bat form screen is the map button (if you map the controller just like the PSX original layout, it should be the left trigger).

Thanks, it does the trick indeed. Now I only need to deal with embarrassment of not trying this particular key.
Although I'm pretty certain on CD version enter could to this as well.

Well, I don´t really have a specific button to use since I use the keyboard. I have tried every button i have on the keyboard.

No need for controller. Try to confirm selection of location with the key that is binded to "eagle eye" function. By deafault it's F(something, 4 or 5 I think). I have eagle eye under TAB and it works.

Thank you!
It was F6.

Something you can live with since it is not something you do all the time.
