Description

This is a core element of keyboard input management within KeymanWeb, typically called automatically during keystroke processing events. For comparison with Developer 'rules' from keyboard source code, in the rule

"a" + "'" > "á"

a keyboard would, after checking that the initial context ("a") matches, use

keyman.interface.output(1, Pelem, "á");

to erase one character "a" and output one character "á", effectively performing the desired replacement.
