Shortcut to character accents

Hello. I'm new to the whole Linux thing and I have something for a topic.

In Windows you can produce characters with accents via a shortcut. For example: " followed by e brings forth . I miss this in Linux. Somebody told me that I should ask for help writing software by myself to make this possible. That's why I opened this topic.

I'm not very experienced with programming. The only thing I ever did is creating a game. It's not even finished. I have a Github account.

I'm hoping to meet someone who gets me through this.

Thanks,

Leon
