keycapsequenties

Keycapsequenties is a term used in discussions of keyboard customization and input design. It refers to the sequences of legends (the marks printed on keycaps) that are associated with a keyboard, including how those legends are organized, displayed, and changed across different layouts or layers. In practice, keycapsequenties describe both the base legends on keys and any additional legends that become visible or active when switching layers, such as function keys or language-specific markings.

Origin and scope: The concept is common in Dutch-speaking communities of mechanical keyboard enthusiasts, interface design researchers, and typer training contexts. It is a descriptive term rather than a formal engineering standard, used to compare how different keyboards present symbols, shortcuts, or multilingual legends.

Types: Static keycap sequences are fixed legends for a single layout. Dynamic or layered keycap sequences involve multiple sets of legends that can be activated by switching layers or modes, enabling different symbols or shortcuts without changing the physical keycaps. Multilingual keycap sequences use separate legend sets for different languages or scripts, often accessible through layer switches or removable keycaps.

Design considerations: Important factors include legibility, font and size of the legends, color coding, and durability of printing. Designers also consider consistency across key sizes (1u, 1.25u, etc.), ease of switching between sequences, and the potential for user confusion if layers are not clearly indicated.

Applications and usage: Keycapsequenties are relevant for hobbyist keyboards, gaming setups, and educational keyboards where visual legends aid learning or shortcut discovery. They are also of interest in studies on readability and ergonomics of keyboard layouts.
