KB backlight problems with Inspiron 5577 gaming

The Inspirion 5577 gaming keyboard is red on a black background. Unless the keyboard is backlit no one can see the letters -- it's that bad, and it is a usabilty issue.

Of course, there is the backlight function, which works just fine except for one thing. It does not stay on permanently (until the end of the session). And when it goes dark, you can't even find the key turn it on again.  And if you use the wrong Key, Windows' intrusiveness with "how can I help you" nonsense can take it out of you.  One has to use a flashlight...

There is a panel where the intensity of the backlight can be changed but not the duration. 

Does anyone know how to change the duration of the backlight?  

In addition, this is an issue that handicapped people and I dare say others are/will be afflicted with, and a solution should be found. (sticky keys are one such...)
