Clearer instructions for adding keywords in search setup

As a user, I want the user interface to provide clear instructions that I need to press the 'Enter' key after typing a keyword in the search setup. This would prevent confusion and getting stuck, as it wasn't obvious that this action was required to validate the keyword and proceed. The 'Next' button was inactive, and I had to go through several troubleshooting steps to figure this out. A simple instruction like "Press Enter after each keyword" would have solved the problem immediately.
