You can't program (correctly) faster than you can think. However, you can practice the translation from thought to code by understanding your language really well and by getting a lot of experience with the kinds of things you do. For example, the first time you code a linked list, it's going to take some time to get used to how it works and to program it correctly. The second time, you might still need to look something up. However, once you got used to the abstraction, you can simply type it down as fast as your fingers allow. This has nothing to do with what your actual goal is but rather it's the process of translating your thoughts to a particular abstraction that you can directly write down in code in a particular framework (the programming language). This abstraction layer varies for different programming languages and you simply need to get used to it and gather experience. I think of it as trying to speak a foreign language, e.g. English for myself. I'll never get faster than in German at saying what I want to say (albeit, there might be cases where English is way more efficient). The entire process is simply limited by how well I'm able to translate thought into the abstraction layer of speech. As everybody will tell you, this skill is greatly enhanced by actually using the language in various contexts until it becomes intuitive.
