Glossary
Mechanical keyboard terms explained for newcomers — the switch, layout, keycap, and build vocabulary the hobby assumes you already know.
#
- 60% layout
-
A compact board with no number pad, arrows, or function row — about 61 keys. Very space-efficient, but you must learn a function layer for arrows and F-keys.
See also: Form factor (layout size), Layer (Fn layer)
A
- ABS keycaps components
-
A common, smooth keycap plastic that can look great but develops shine where fingers touch it most. Frequently what stock budget caps are made of.
See also: PBT keycaps, Keycaps
- Actuation force switches
-
How hard you press, in grams-force, before a key registers. Lighter switches tire fingers less; heavier ones resist typos. There is no 'best' — only what suits you.
See also: Linear switch, Tactile switch
C
- Clicky switch switches
-
A tactile switch that also clicks audibly. Often labeled 'Blue'. Satisfying but loud — reconsider for offices or shared rooms.
See also: Tactile switch, Linear switch
F
- Form factor (layout size) layout
-
The size class of a keyboard by how many keys it has — 100% (full-size), TKL, 75%, 65%, 60%. Smaller boards save desk space by moving keys onto layers.
See also: Tenkeyless (TKL), 60%, Layer (Fn layer)
G
- Gasket mount build
-
A construction style that cushions the typing surface on soft gaskets for a softer feel. Increasingly common; not required for a good first board.
See also: Tray mount
H
K
- Keycap profile components
-
The shape and height of keycaps (e.g., Cherry, OEM, SA). Sculpted profiles contour to your fingers; uniform profiles are the same shape on every row.
See also: Keycaps
- Keycaps components
-
The caps you actually press. Their material and profile change how a board feels, sounds, and looks — often the easiest meaningful upgrade for a beginner.
See also: PBT keycaps, ABS keycaps, Keycap profile
L
- Layer (Fn layer) layout
-
A second set of key functions reached by holding a modifier, usually Fn. Smaller boards rely on layers for arrows, media, and function keys.
- Linear switch switches
-
A switch with smooth, bump-free travel. A common first choice for gaming and fast typing. Often labeled 'Red'.
See also: Tactile switch, Clicky switch, Actuation force
- Lubing modding
-
Applying a thin lubricant to switches and stabilizers to reduce scratchiness and rattle. A common first modding project once you're comfortable opening the board.
See also: Stabilizers, Linear switch
M
- Mechanical switch fundamentals
-
An individual spring-loaded mechanism under each key, as opposed to a single rubber membrane sheet. Each key registers independently, which is what gives mechanical keyboards their consistent feel and longevity.
See also: Linear switch, Tactile switch, Clicky switch, Membrane keyboard
- Membrane keyboard fundamentals
-
A keyboard where keypresses are detected through a single flexible rubber/silicone layer. Cheaper and quieter but mushier and shorter-lived than mechanical — the thing most people are upgrading from.
See also: Mechanical switch
P
- PBT keycaps components
-
A durable, slightly textured keycap plastic that resists the greasy shine ABS develops. Usually the recommended upgrade.
See also: ABS keycaps, Keycaps
Q
- QMK / VIA firmware
-
QMK is open-source keyboard firmware; VIA is a simple app to remap keys and build layers without programming. A genuinely useful feature to look for on a first board.
See also: Layer (Fn layer)
S
- Soldered build
-
A board with switches permanently soldered to the PCB. Cheaper and very secure, but committing to a switch choice. Fine once you know what you like.
See also: Hot-swap
T
- Tactile switch switches
-
A switch with a bump you feel when the key registers, without a click sound. Often labeled 'Brown'. A good middle ground for typists.
See also: Linear switch, Clicky switch
- Tenkeyless (TKL) layout
-
Full-size minus the number pad — about 87 keys. A popular, low-risk first step down from a full-size board.
See also: Form factor (layout size), 60%
- Tray mount build
-
The most common budget construction: the board screws into posts in the case. Perfectly fine for a starter keyboard.
See also: Gasket mount
W
- Wireless (2.4 GHz vs Bluetooth) connectivity
-
2.4 GHz uses a USB dongle and feels near-instant (good for gaming); Bluetooth connects to phones and tablets conveniently with slightly more delay. Many boards do both plus wired.
