As a first post, I thought I would start with something fun – moving the mouse! To be noted – this is not the same as simulating user input. I’ll save that for a later post.

More features may get added later – timers, sound alert, maybe others. For now, here is a simple script that will either move the mouse from left to right, or top to bottom.

All comments welcome!

<#
.Synopsis
Moves the mouse cursor either from left-to-right
or top-to-bottom indefinitely.
.EXAMPLE
.\Move-Mouse_v1_0.ps1 -MotionType LeftToRight
.EXAMPLE
.\Move-Mouse_v1_0.ps1 -MotionType TopToBottom
.EXAMPLE
