Why do keyboard and letters not match in NetBeans?

Question

I am a beginner programmer trying to learn PHP, but when I installed NetBeans the entire IDE produces garbled letters (ie. all the letters I type don't correspond to the ones on the keyboard) for all of my applications. For example I tried to type "/" but instead it produces ",". Anyone can tell me what is wrong with it? Many thanks in advance!

Answer 1

Use Alt+Shift key combination, that should switch the keyboard layout.

Answer 2

Your keyboard layout is probably not in the language you desire. Ensure your keyboard layout matches within the OS.
