How to adjust the bightness of the back light?

In the bottom row of keys, there's one to the right of the space bar that has an icon on it that looks like the sun. It's between the Function key (FN) and the Control key (Ctrl). According to the user's manual which came with the keyboard, tapping that key will turn the light on or off. For a "breathing light" (cycle between bright and dim), hold down the FN key and tap the sun icon. Release the FN key, and the light will cycle, from bright to dim to bright to dim etc. - the so-called "breathing light" (I don't use it, as I find it distracting). To simply change the brightness level, hold down the FN key and tap the PU key (Page Up) to brighten the light, or tap PD (Page Down) to dim it. When you have the brightness you want, release the FN key. Works for me ... maybe make a note of it?

what are the dimensions of each key?

Most keys are 5/8" square (16 mm). Judge the large keys from this.

Since seller did not send manual and a reviewer explained fn key, anyone knows what keys ps, sl , pb and pu are for ?

PS - Print Screen SL - Scroll Lock PB - Pause/Break PU - Page Up

does the keyboard light have a time out?

The light is on unless you turn off your computer, put your computer to sleep or there is a key on the keyboard that lets you choose to have the light off.
