Re: Layers and NVDA
Thanks for this, Luke. I am a complete novice as I only heard about thistoggle quoted messageShow quoted text
concept fo layers last Saturday! Please don't take it that I know anything
about it yet. I will pull back my concept as you clearly indicate it as
misplaced. I agree that the information I have gathered so far simply permits
extra keystrokes that might otherwise interfere with the basic set of keys
that drive the screen reader.
I will study the detail of your response and I am sure to learn more from it.
All the best,

Honestly I have not heard the term layering used in the way that you are
There is programmatic layering, which is mainly about isolating different
portions of a program into higher and lower functions that only know about
the layer directly above/below them.
There is screen reader keyboard layers, which is when one screen reader
keyboard command (gesture, in NVDA terms), causes other keys on the keyboard
to have effects other than they usually would.
For example, the Developer Toolkit add-on for NVDA does this.
Read more about it here:
You press a certain key sequence, after which other keyboard keys now do
something dedicated to that add-on, instead of whatever they did before. It
is a way of using more keyboard commands than you normally have keys
available to use conveniently.
But I don't think that's quite what you're talking about, at least not
entirely, as you seem to be bringing in other concepts of programs
interacting with each other, which I have not heard called layering.
Then again, there is much I don't know. You may be better off asking about
this on either the nvda-devel or nvda-addons lists.
