Key Extended by Simon Daykin of Byte-sized Computing is a free keyboard-key dingbat font built around outlined computer keycaps. Each symbol uses a squared top, clipped corners, and a flared base to suggest a raised plastic key. The inner signs are simple and sturdy.
The shared keyboard motif lets interface diagrams and software manuals use the symbols as both labels and small illustrations. Gaming graphics, tech event posters, and computer-themed merchandise can draw on the same familiar hardware shapes.
