| This directory contains the raw data for mapping between different | |
| keyboard codes. Naming if often based on the US keyboard layout, but | |
| does not indicate the symbol actually generated by the key. | |
| The columns currently in this data set are: | |
| Linux | |
| ----- | |
| Name and value of the hardware independent keycodes used by the linux | |
| kernel and exposed through the input subsystem. | |
| References: linux/input.h | |
| macOS | |
| ----- | |
| Low level key codes as exposed by Mac OS X/macOS. | |
| References: Carbon/HIToolbox/Events.h | |
| PC scan code sets | |
| ----------------- | |
| Scan codes for the three orignal PC keyboard generations: | |
| Set 1: XT | |
| Set 2: AT | |
| Set 3: PS/2 | |
| The sets include codes for modern keys as well and not just the keys | |
| present on those original keyboards. | |

| USB HID | |
| ------- | |
| Codes as specified by the HID profile in USB. | |

| Windows Virtual-key codes | |
| ------------------------- | |
| The low level, hardware independent "VKEYs" exposed by Windows. | |
| References: mingw32/winuser.h | |
| XWin XT | |
| ------- | |
| X11 keycodes generated by the XWin server. Based on the XT scan code | |
| set. | |

| Xfree86 KBD XT | |
| -------------- | |
| X11 keycodes generated by the Xfree86 keyboard drivers. Based on the XT | |
| scan code set. | |

| X11 keysyms | |
| ----------- | |
| Corresponding X11 keysym value(s) for a US keyboard layout. | |
| WARNING: These columns represent symbols, not physical keys, and should | |
| be used with extreme care. | |
