How To Hide Or Show .NET Tabs Programmatically

I worked in the front line of the software development industry for over 20 years, previously I was a hardware engineer followed by applications consultant. For the last 10 years of my watch on software development I worked with the Microsoft .NET development framework, both in Winforms and with ASP.NET.

However as I move into the evening of my life I have been forced to take early retirement. Ii has recently been confirmed that I am afflicted with Parkinson's. This has been developing for some time, during which my hand tremors gradually deteriorated to the point where using a computer mouse became impossible. Trying to point/click on a tiny icon or menu option when your hands figure they can do a merry dance ultimately becomes intensely frustrating, and earning a living as a software developer reaches the stage of impossibility.
