KEYBOARD(3): keyboard sequences



Text input as implemented by Ink permit composition of keys. To compose a key, type Alt and then one or more keys. If the sequence of keys is a prefix of a valid sequence, the keys will not be shown, and will be collected. Once a valid sequence has been typed, the corresponding key will be inserted instead of the full sequence. If the sequence is not valid, the original keys typed will be shown, and composition will finish.

The composition sequences are those of Plan 9 from Bell Labs, but for typing of unicode code points directly, which are usually provided using the underlying terminal OS keyboard facilities. From the Plan 9 man page...
