Keyboard Tenting (Wrist Pronation)
Recently (2016-07-16), had hand discomfort again. On keyboard for too long. This time, the cause is pronation.

How do i know it's pronation problem? Because if i rotate forearm the opposite direction (e.g. put hands on desk, palms up.), there's big comfort, relief.
My current keyboard, the Truly Ergonomic keyboard 2016 , is flat. It causes pronation problem if put hands on keyboard 8 hours a day.
To solve the pronation problem, you need keyboard with โtentingโ, meaning, raised in middle.

So, is tenting really important?
Yes, if you use keyboard for long period of time.
How long is long? Hard to say. But for me, i sit in front of computer, for 12 hours a day, in past years. I try to not leave my hand on keyboard when not actually typing. Using regular mouse is also a problem. Basically, anything that makes your palm face down. (i get up and take a walk for 10 min every 2 hours, but has been lazy on this in past 3 months. (wow, that's probably why!))
Here is keyboard with raised middle that i recommend
see Best Ergonomic Keyboards, Xah Pick for keyboard with tenting feature.
Got a Kinesis Advantage2 two months ago (2016-07), and it cured my pronation problem!
