Let’s say you typed a character that indicates a particular keyword in a programming language and after that you press a combination of keys from the keyboard to complete the keyword.

Now if IntellijIDEA is unable to give you hints for the given word (whatever you have typed) with keywords then it means that the keyword either doesn’t start with that partial word or auto complete feature needs case sensitive search.
