From the official website:
- Remote terminal application that allows roaming, supports intermittent connectivity, and provides intelligent local echo and line editing of user keystrokes. Mosh is a replacement for SSH. It is more robust and responsive, especially over slow connections such as Wi-Fi, cellular, and long-distance.
Install the package, or AUR for the latest revision.
Mosh has an undocumented command line option
--predict=experimental which produces more aggressive echoing of local keystrokes. Users interested in low-latency visual confirmation of keyboard input may prefer this prediction mode.
