What do all the key functions do ? - Belkin Multimedia (f8e820-blk-usb) Keyboard

Depending on the calculator, some are colour coded, so to get the function you want, you hit the associated colour function key and then the key with the function. Some calculators have two different colours, so each key has three functions assigned to it, one without a function key, one with colour key 1, and one with colour key 2.

Good luck,

The purpose of a laptop's function key is to activate the secondary function of any dual-purpose key.

The function key can accidentally be locked into place if you hit the wrong combination of keys so that all of the keys only perform their secondary function.

The exact process for unlocking the function key will vary depending on the make and model of your laptop and whether you have recently used an external keyboard.

Check the manual that came with your laptop and locate the section on the function of each keyboard key.

Open a Web browser and navigate to the support section of the laptop manufacturer's website if you do not have the manual that originally came with your laptop.

Function keys are special keys used for assigning program shortcuts and specialty tasks to the keyboard.
They are located at the top of most keyboards and labeled "F1" through "F12."
Some keyboards may only feature 10 function keys, while others may have as many as 18. These keys often go unutilized by the average computer user, but they may have very important tasks for some users, which can lead to problems when the keys do not respond.
Fixing nonresponsive or malfunctioning function keys is quite simple, and should only take a few minutes.

Connect your keyboard to your computer, and power it up.
Open a program that uses the function keys such as Microsoft Word or Microsoft Excel. Check your keyboard for an "F-Lock" or "Function Lock" key.
This key is used to toggle function-key support; when it is toggled on, the function keys will not work.
Press the "F-Lock" key and then try using a function key in the selected program. "F1" is a good key to test, because it is set to open a "Help" document in all Microsoft software.
If the key does not work, press the "F-Lock" key a second time, and test the keys again.
If the keys still do not work and you are running the Windows 7 operating system, you may need to install a "hotfix" from Microsoft to fix the key functionality.
