This is made possible by also allowing the second
argument to be "x" or "y". We supply "y" as the
default to retain the current, more commonly
desired behavior.
This adds an excmd interface to the Web Speech API (TTS), which allows
users to read text out and set voice and parameters via config options.
Excmds:
- ttsread: reads out the given text or element content (CSS selected)
- ttsvoices: lists available voice names (can be used in the
'ttsvoice' option)
- ttscontrol: stops the current reading (should also pause/resume,
but that doesn't seem to work right now)
Config options:
- ttsvoice: the name of the voice to use
- ttsrate: (0.1-10)
- ttsvolume: (0-1)
- ttspitch: (0-2)
Also the ;r hint submode is added which reads the textcontent of the
element with the configured voice
