ISO layout
Provided by the ASK Keyboard Dictionary
The "ISO" physical layout is one of the two main keyboard layouts introduced by the Enhanced layout alongside the ANSI layout that together remain the base of most keyboard layouts. It is named after the International Organisation for Standardisation and was primarily intended for EMEA countries, Canada (bilingual) and South America (Latin American Spanish). Compared to ANSI, ISO physical layout has a smaller (1.25-unit) left shift key and a vertically massive (2-unit tall) enter key in the shape of a backwards and upside-down L. Typically, the right Alt key is also labelled as "Alt Graph" (Alt Gr).
