That means, clients that use library or +toolkit routines to interpret keyboard events automatically use all of XKB +features; clients that directly interpret the state field of core protocol +events or the keymap direcly 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. -- cgit v1.2.3
