How could we make sure that this list of gestures is complete?

It probably isn't unfortunately.

I haven't seen the console send a \n on return, but there's no reason why I couldn't add it...

Link to issue number:
Split from #9646 (builds on #9614).
Summary of the issue:
Currently, in consoles with UI Automation enabled:
_isTypingflag is not cleared on the console, so new text is not announced immediately.Description of how this pull request fixes the issue:
The
speech.curWordCharsbuffer is cleared when atypedCharacterof enter or tab is received. This prevents NVDA from speaking partially-typed words (during tab completion) or the last word of a command (when enter is pressed). This approach will need to be modified once #8110 is merged, as it significantly changes handling of typed words.The interrupt characters control+c, control+d, and control+break have been bound to the
script_clear_isTypingscript onNVDAObjects.UIA.winConsoleUIA.Testing performed:
Tested "speak typed words" on Windows 10 1803 and 1903. Tested console performance with many
textChangeevents on Windows 10 1903.Known issues with pull request:
See #9646 for all known console UIA issues to date.
Change log entry:
None.
