While all keyboards offer the necessary QWERTY layout of keys for everyday typing, sometimes typing isn't your main concern. Gaming keyboards are designed for competitive use and emphasize things office keyboards don't.

Gaming boards are equipped for maximum specialization and control, optimized for specific styles of gameplay, and built to exacting standards of responsiveness and durability. They also appeal to the gaming aesthetic with designs that impress and intimidate with pulsing backlighting and dramatic RGB color schemes.

Premium gaming models almost exclusively use high-grade mechanical key switches and sculpted keycaps, and offer scads of customizable features such as programmable macro keys, textured WASD keys, and swappable keycaps. Others let you tweak the color and intensity of the backlighting to make finding certain keys faster and personalize the look of your keyboard. Cheaper boards usually have just one color of backlight, but as you move upmarket you find programmable RGB lighting customizable by zone or even by individual key (so-called "per-key RGB").

Anti-ghosting is an essential feature, allowing a keyboard to register multiple keystrokes hit at the same time—a feat not all standard keyboards can perform. Other extras include USB pass-through ports or audio connections that simplify the process of connecting peripherals or headphones to a desktop PC whose ports may be inconvenient to reach under a desk.

Finally, any gaming keyboard worthy of the name comes with dedicated software and discrete keys for triggering macro commands, letting you save and play back complex strings of commands with a single keypress. The number of macro commands you can save, and the ease with which you can create them, varies from one model to the next; our reviews are handy for summaries of this kind of software. These aren't the sorts of customization features that everyone will use day to day, but for players who invest time and money into gaming, these keyboards offer a competitive edge. Again, check out our guide to gaming keyboards for more on gaming software.

Not all keyboards are created equal. In fact, not all keyboards are even laid out the same (and we're not referring to the standard QWERTY key layout versus the Dvorak arrangement of some early ergonomic models).

Most mainstream and gaming keyboards offer a 10-key numeric keypad at right. Rarely found on laptops smaller than 15.6 inches, keypads are a necessity for anyone who frequently tallies numbers or enters data into a spreadsheet. So-called tenkeyless or TKL models, especially popular in the gaming keyboard segment, slice off the numeric pad in the interest of saving desk space and keeping your typing and mousing hands closer together. If you want to go even smaller, so-called 60% keyboards eliminate even more extra keys. Check out our 60% keyboard guide for everything you need to know about them.

Smaller distinctions include the placement of the cursor directional arrows and Home, End, Page Up, and Page Down keys. Additionally, most current keyboards have basic media-control features such as volume, play/pause, and next/previous track keys. These are typically dedicated buttons located above the numeric pad or built into the top row of function (Fn) keys as shared-key shortcuts. Bonus points if a keyboard maker implements the volume control as a dial or roller, as seen on some high-end Corsair, Das Keyboard, and HyperX models.

If you prefer an unusual keyboard layout or just want to switch up a key or two, you may want to remap your keyboard. Our guide to keyboard remapping on Windows explains how to go about doing that.

To help stave off carpal tunnel syndrome and repetitive stress injury, many keyboards are available with designs that put your hands into a neutral position as you type. The result is not only greater comfort, but reduced stress to joints and tendons, ultimately helping you avoid painful inflammation and the potential for expensive surgery. Ergonomic features can range from the simple (padded wrist rests) to the elaborate (a key layout sculpted to curve and slope, or a split design).

One very important ergonomic feature to look for is the ability to perform angle adjustment. This is usually accomplished by folding or flipping two plastic feet on the back of the keyboard to alter its angle relative to your wrists and forearms. Many keyboards—not only models designed specifically to be ergonomic—have these feet, and research has shown that the traditional uphill tilt is actually not ergonomically ideal. It's better to experiment with them until your keyboard is flat or even angled slightly away from your wrists. (See our guide to ergonomic keyboards.)
