The computer keyboard is a primary input device for text entry, navigation, and command execution. Modern keyboards integrate advanced switch technologies, layouts, connectivity options, and firmware features that improve typing efficiency for everyday users and deliver speed, accuracy, and responsiveness for gaming.
This Knowledge Base article provides a technical, practical overview of keyboard technologies, features, and commonly used shortcut commands that enhance day-to-day productivity and provide advantages in gaming environments.
A keyboard converts key presses into digital signals interpreted by the operating system or application. Keyboards consist of:
Key switches (mechanical, membrane, or optical)
Controller/firmware (handles key scanning, debounce, macros)
Key matrix (rows/columns detecting presses)
Connectivity module (USB, 2.4 GHz RF, Bluetooth)
Optional software (remapping, macros, RGB profiles)
Key performance characteristics include actuation force, travel distance, debounce time, rollover, and polling rate.
Common in office keyboards
Quiet and cost-effective
Moderate durability
Pros: Silent, affordable
Cons: Less tactile feedback, slower response
Individual switches per key (e.g., linear, tactile, clicky)
High durability (50M+ keystrokes)
Precise actuation
Types:
Linear: Smooth, fast (gaming)
Tactile: Feedback bump (typing)
Clicky: Audible click (feedback-focused)
Infrared light-based actuation
Extremely low debounce and latency
Resistant to wear
Pros: Fastest response, consistent
Cons: Higher cost
Full-size (104/105): Includes numpad
Tenkeyless (TKL): No numpad, compact
75% / 65%: Space-saving with arrow keys
60%: Minimal footprint (gaming)
Ergonomic/Split: Reduced wrist strain
Zero battery dependency
Lowest latency
Preferred for gaming
Near-wired performance
Low latency gaming support
Multi-device pairing
Power-efficient
Higher latency (office use)
NKRO (N-Key Rollover): Multiple simultaneous key presses
Prevents missed inputs
Assign sequences to a single key
Boost productivity and gaming efficiency
Visibility in low light
Profile/status indicators
Volume, playback, brightness
Access via Fn key layers
Key remapping
Profile switching
Macro recording
Low actuation distance (fast response)
High polling rate (1000 Hz+)
Dedicated macro keys
Game mode (disables Windows key)
On-board memory (profiles without software)
