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.

Not a UK layout keyboard

Probably wont suit a UK user or country where UK layout keyboards are used. It is not clear without looking closely at the picture what country this keyboard is intended for. Although being sold on the Amazon UK website this is not a UK layout keyboard. ie. there is no £ sign etc. and hash and quotes keys are swapped. Shame because the backlighting and large font makes the other keys easy to find in low light.

Large text keyboard

It’s a nice keyboard and it’s easy to see but the two keys that are highlighted are the wrong way around. The @ and the “ keys are in the wrong places. I know where they are now but this is incredibly irritating if you press the @2 key you get “2 and the “ ‘ key you get @‘ this is really really annoying.I am visually impaired and this is not what you need. It spoils what is a reasonably good keyboard but I would say it is also quite flimsy cheap plastic.

I bought a keyboard from Asda that was better quality

Key spacing is dreadful and sometimes almost unusable.Keys rattle and you seem to have to make stabbing movement while typing.I am sorry but this keyboard really is the worst backlit keyboard I have ever purchased,the only redeeming feature is the backlight.
