Er, so to clarify, I think the text tool should be using Char events to
add characters into text objects and Keypress events to initiate
I'm sure you know this already but remember that Char events can be
generated from sources other than the keyboard, e.g. OCR,
speech-to-text, chorded keyboards, handwritingr recognition, etc.,
