[i18n-activity] What do 'character key' and 'printable' mean?

r12a has just created a new issue for https://github.com/w3c/i18n-activity:

== What do 'character key' and 'printable' mean? ==
Success Criterion 2.4.11 Character Key Shortcuts§ 
https://www.w3.org/TR/WCAG21/#character-key-shortcuts

> If a keyboard shortcut consisting entirely of one or more character keys is implemented by the content, then a mechanism is available to turn it off or to remap it to a shortcut that uses at least one non-character key. 

https://www.w3.org/TR/WCAG21/#dfn-character-key

> single printable Unicode code point, any keyboard character that is printable, i.e. letters of the alphabet including capitals, punctuation, numbers, and symbols
> 
> Note that the Space and Enter keys, which return empty spaces rather than characters, are not character keys.

It would be better to more clearly define what is and isn't a 'character key', and what 'printable' means.  (The UI Events specs may help?)  I'm not clear why the space character couldn't be a shortcut key – see it's use, for example, in Thunderbird to scroll down messages then on to the next message.
