Examples
By CEFR Level
- I spilled tea on my keyboard and now the 'A' keycap is sticky.
- The letter wore off the keycap.
- You can order replacement keycaps if some letters fade.
- To clean it, you need to gently pull off the keycap first.
- Mechanical keyboard enthusiasts often invest in custom, artisan keycaps for a personalised look and feel.
- The texture of these PBT keycaps prevents them from developing a shine over time.
- The group buy for the new double-shot, sculpted SA profile keycap set closed after reaching its funding goal.
- Ergonomics are influenced not just by the keyboard shape, but also by the keycap profile and sculpting.
Learning
Memory Aids
Mnemonic
Think of a KEY on a keyboard wearing a CAP or hat. The KEYCAP is the hat that sits on top of the mechanism.
Conceptual Metaphor
A KEYCAP IS A FACE/INTERFACE (it presents the identity/function of the underlying switch to the user).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'ключевая крышка'. The Russian equivalent is typically 'клавиша' for the whole key, or more technically 'колпачок клавиши'.
- Do not confuse with 'keychain' (брелок).
Common Mistakes
- Using 'keycap' to refer to the entire key mechanism (which includes the switch and stem).
- Spelling as two words ('key cap'). While sometimes seen, the closed compound is standard in technical contexts.

FAQ
Frequently Asked Questions
It is standardly written as one word (keycap), especially in technical and enthusiast contexts, though 'key cap' is sometimes seen.
Most keycaps are made from plastics like ABS (Acrylonitrile Butadiene Styrene) or PBT (Polybutylene Terephthalate), which differ in texture, durability, and sound.
On many modern laptops, keycaps are not designed to be easily removed by users and are often part of a low-profile 'chiclet' mechanism. Replacement is usually more difficult than on a mechanical keyboard.
It's a manufacturing process where the keycap body and the legend (letter/symbol) are made from two different colors of plastic molded together. This makes the legend extremely durable and prevents it from wearing off.
