IMO this should not be done by the kernel, but by the application.
Reasons: - actually, there is no key "a" etc that is pressed, but "1" etc. - you loose ability to keep the display up to date according to the pressed key sequence while composing characters, otherwise. - it is easy for the application to check the timing of the keys pressed and produce the desired characters instead [poll (2)]. - not all projects using the keyboard in question will need the sequence-to-character conversion You describe. e.g. cash register.
