Edit Text in Mac Book Pro

I can't Edit the any text in new page or Existing page but i can Delete the text. Could you please let me know the reason. I am new to bootstrap studio application.

Double click the text in the visual preview window. I'm guessing that you're trying to edit it in the HTML window and it doesn't work that way. Let me know if that is the issue or if you're still having issues please give an example of what it is you're trying to edit so we can try to recreate it.
