Description
This is a core element of keyboard input management within KeymanWeb introduced with version 10. It is utilized to manage the deletion of context in a deadkey-aware manner, in parallel to keyman.interface.fullContextMatch. For comparison with Developer 'rules' from keyboard source code...
store(pair_1) 'uU'
store(pair_2) 'lL'
c Lots of keyboard rules...
'nul' dk(nothing) + '.' > nul
would have a rule output as follows:
// Context is length four (three characters + one deadkey), so we delete all four.
keyman.interface.deleteContext(4, element);
