Learn how to type well (>30wpm). Literally everything else is secondary. You don't have to be the fastest or most accurate typist, but not having to look at the keyboard while typing pretty quickly and accurately is foundational.

Not having to use the mouse for common tasks (closing a window, switching applications, etc...) is another core skill.

Everybody else's comments focus on important stuff but I've seen programmers absolutely hobbled by not having these basic skills.
