  Virtual, Mixed, and Augmented Reality (XR) technologies hold immense
potential for transforming productivity beyond PC. Therefore there is a
critical need for improved text input solutions for XR. However, achieving
efficient text input in these environments remains a significant challenge.
This paper examines the current landscape of XR text input techniques, focusing
on the importance of keyboards (both physical and virtual) as essential tools.
We discuss the unique challenges and opportunities presented by XR,
synthesizing key trends from existing solutions.
