Contents of README:The core protocol interpretation of keyboard modifiers does not include direct support for multiple keyboard groups, so XKB reports the effective keyboard group to XKB-aware clients using some of the reserved bits in the state field of some core protocol events. This modified state field would not be interpreted correctly by XKB-unaware clients, so XKB provides a group compatibility mapping which remaps the keyboard group into a core modifier mask that has similar effects, when possible. XKB maintains three compatibility state components that are used to make XKB-unaware clients(*) work as well as possible: - The compatibility state which corresponds to the effective modifier and effective group state. - The compatibility lookup state which is the core-protocol equivalent of the lookup state. - The compatibility grab state which is the nearest core-protocol equivalent of the grab state. Compatibility states are essentially the corresponding XKB states, but with the keyboard group possibly encoded as one or more modifiers. Modifiers that correspond to each keyboard group are described in this group compatibility map. ---- (*) The implementation of XKB invisibly extends the X library to use the keyboard extension if it is present. That means, clients that use library or toolkit routines to interpret keyboard events automatically use all of XKB's features; clients that directly interpret the state field of core-protocol events or the keymap directly may be affected by some of the XKB differences. Thus most clients can take all advantages without modification but it also means that XKB state can be reported to clients that have not explicitly requested the keyboard extension. |
