Is your feature request related to a problem? Please describe.

For deaf-blind users, who are interacting with the computer via a refreshable Braille display, the information given via speech is often not available. What is on the Braille display is what matters. The Braille viewer is aimed at sighted assistants who will then be able to get a visual Braille representation of the information the user is getting.

According to the user guide in NVDA 2021.3.1, it is only possible to turn the Braille Viewer on and off via the Tools menu. This is something that can be a bit complicated to quickly explain to a sighted helper.

Describe the solution you'd like

A configurable command in the Input Gestures dialog to toggle the Braille Viewer similar to what we have for the Speech viewer.

Describe alternatives you've considered

Using the Speech viewer instead. Is it the same as what is given in Braille? I haven't been able to get sighted verification, so if this is the case then the issue may be closed.

Additional context

As stated above, this issue may be irrelevant if the Speech viewer can be used instead.
