Keyboards are becoming extinct

As a bit of background, I'm 70+ years old and my first experience with a keyboard was typing class in high school circa 1964.  The keyboard training helped immensely as I got involved with computing in the 70's with a printing terminal (think of an advanced teletype) interacting with a remote system, then CRT terminals on a variety of systems, leading up to an IBM PC circa 1981.  
So navigating a plethora of user interfaces with a keyboard is old hat, so to speak.
Through the 80's, we used keyboard and mouse with a graphical user interface and some de facto standards or interface behaviors became common:

• Use of the Tab key to move the highlight from field to field
• Use of the Spacebar to select an element on the screen, such as, checking the highlighted checkbox, selecting one of a group of options (radio button), or executing the highlighted command (as in 'clicking on the Submit' button).
• Use of the arrow keys to highlight different options
• As well as various editing functions of select all (ctrl-a), cut (ctrl-x), paste (ctrl-v), and copy (ctrl-c).

I, like many of my colleagues, continued to prefer the keyboard to the mouse when possible as it is much faster and less work for many tasks.  Moving the hand to the mouse, then shifting focus to the cursor and driving the pointer around the screen to do what you need to do is way more taxing than simply pressing Tab and typing in the next field of data on a form, for example.

Then several other pointer technologies emerged with various pluses and minuses:

• TrackPoint "titmouse" or "eraser head" pointer in the keyboard which actually worked pretty well once you got used to it.  
• Touchpad
• Digital pens
• And finally Touch Screens

However, today, it seems that with all these pointing methods, the ability to even use a keyboard has been deprecated in many user experiences.  I have encountered many web pages that are maddeningly unfriendly if you prefer using a keyboard.

The one that prompted this rant is proxyvote.com.  It actually works pretty well using the keyboard with one glaring deficiency!  There is absolutely no visual indication of which option on the screen is currently highlighted!

In the above image, the For button is "active".  By that I mean, if you press Spacebar, the For option will be selected (shown in inverse).  But you have no way of knowing beforehand which one is active!  

You can fill out this proxy form quickly by 1st clicking on the 1st For, then Tab, then Space to select the next one, tab/space, tab/space down the form.  But you have to keep place in your head because there are no visual clues on the page to guide you.  

Contrast this with:

where you can see that the Mail option is active.

And that is the rant - no one tested the usability of this page using a keyboard!

This is happening more and more where the means of input is touch screen only, hence, no keyboard needed...
