Within X11 each user input (mouse click or key press) is an X Window System event. Xnee records these events into a file. Later Xnee is used to play the events back from the file and into an X Window System just as though the user were operating the system.{{cite web

Xnee can also be used to play or distribute user input events to two or more machines in parallel.

As the target X Window application sees what appears to be physical user input it has resulted in Xnee being dubbed “Xnee is Not an Event Emulator.”{{cite web

As Xnee is free software, it can be modified to handle special tasks. For example, inserting time stamps as part of the playback.{{cite web|url=https://www.cs.cmu.edu/~gghartma/final-report.pdf
