Editing Keyboard profile (section)

===Numbering===
[[File:Row numbers in KPT keycaps.jpg|thumb|250px|KPT used R4 for the top row and R1 for the bottom, per the mould numbering]]

Most keyboards have four row profiles, for the alphanumeric rows, with the function key and space bar rows borrowing their profiles from the adjacent rows. The space bar is often higher and convex.

The ISO/IEC 9995-1 standard labels rows alphabetically starting with the space bar row as row A, and the bottom alphabetic row as row B, etc. The standard also mandates that rows above the alphanumeric section start with K and that rows below the space bar be labelled from Z backwards.

Several manufacturers do use ISO numbering, or just ''mostly'' ISO numbering. Other manufacturers label rows in other ways:
