Now I am not sure how familiar you are with the terminology that is used in the gaming keyboard field, but below is a list words that you will come across with regards wholesale gaming keyboard to gaming keyboards.

WSAD - This is the four keys that you use to control movement which is typically your W, S, A & D keys.

ANTI-GHOSTING - Typically in a standard keyboard (or dome switch keyboard), the design is in such a way that the keyboard uses columns and rows of wires. Through this design the results that occur can be inaccurate when lots of keys are pressed at once. When this happens the dropped keys become "ghosts". With keyboards that have anti-ghosting capabilities, they use a small dab of carbon at each switch site to prevent the contact of the keys from shorting the rows or columns of wires. In doing so, this allows the keyboard to decode each key press separately.

MACROS - A macro is a collection of operations and property values that can be applied to an existing visualization or visualizations. So in other words macros are not linked to the objects or visualizations to which they are applied but when they are used, the operations or property settings will be applied to the objects currently selected. This means that property settings can be applied to multiple visualization types, unlike property settings in styles.

OPTICAL - Optical is basically a device used for producing or controlling light. So if you took an optical mouse for example, it would be a mouse that produces light and in doing so uses the light to register it's movement on your computer.

ULTRA POLLING - Ultra-polling in gaming mice increases the amount of times the firmware on a mouse reports it's tracking data to the computer to 1ms (1000hz). In doing so, it reduces the interval between each transmission of movement calculations and therefore giving the cursor on the screen a smoother and more precise feel with increased responsiveness.
