class Reline::KeyStroke
Constants
- CSI_INTERMEDIATE_BYTES_RANGE
- CSI_PARAMETER_BYTES_RANGE
- ESC_BYTE
- MATCHED
Input partially matches to a key sequence
- MATCHING
Input exactly matches to a key sequence
- MATCHING_MATCHED
Input matches to a key sequence and the key sequence is a prefix of another key sequence
- UNMATCHED
Input does not match to any key sequence
