Keyboard Layouts
The PC keyboard changed over the years, often at the launch of new IBM PC versions.
| Name | Keys | Description | Image | |
|---|---|---|---|---|
| PC/XT | 083 | original left-hand side function key (F key) columns, F1 through F10; electronically incompatible with PC/AT keyboard types | ||
| PC/AT | 084 | additional |
||
| Enhanced | additional navigation and control keys; 12 F keys in separate row along top, grouped F1-4, F5-8, and F9-12. Early models of Enhanced keyboard (notably those manufactured by Northgate Ltd.) maintained the layout with function keys on the left side, arranged in two columns of six pairs. This layout was more efficient for touch typists but was superseded in the marketplace by that with F-keys along the top. There are different versions of the Enhanced keyboard layout: | |||
| 101 | standard US layout | |||
| 102 | additional key to the left of the Return key for European layouts | |||
| 103 | additional 2 keys (one to the left and one to the right of the space bar) for the Korean layout | |||
| 104 | Brazilian ABNT NBR 10346 variant 2 (alphanumeric portion) and 10347 (numeric portion). | |||
| 106 | additional 5 keys (one above the tab key, one to the left of the right Shift key, one to the left and two to the right of the space bar) for the Japanese layout | |||
| Windows | additional Windows key (×2) and Menu key added (one Windows key to the right of the left control key, the other and the Menu key to the left of the right control key). The Windows keyboard was introduced for use with the Windows 95 operating system. Most modern PCs, whether supplied with Windows or not, are now delivered with this layout. Like the Enhanced layout, the Windows keyboard layout differs from region to region: | |||
