Ratcaps and Ratkeys were designed as a set of highly-legible keycap fonts for use in software and systems documentation destined for in-house printing. They were specifically designed for clarity and legibility even on low-resolution (300 dpi) laser printers. Ratcaps consist of representations of the basic alpha-numeric keyboard keys. Ratkeys contains the special function and modifier keys. Both fonts also come in a 3D-effect version.
