Discussion:
Using here, I cannot enter the accessible buffer https://user-
The issue is that here, the default tab behavior is to focus the terminal tabs element edit: hard to repro, that's not the cause
ok this happens when is not applied to . See here that the buffer editor does get focused here, but you cannot see it https://user-
Repro: run some commands - - - Try to wasn't applied to so the accessible buffer isn't visible

Currently when you use navigate accessible buffer you get a quick pick with the options, I expected changing these to scroll to the position without accepting it, and escape to revert to the original scroll position.
As part of this, providing ~1/3 of the viewport of context above would also be good
We'd need to think about how we to communicate the preview information to a screen reader user, as a pre"view" is usually visual
I don't think making this available to the screen reader makes sense, it would just complicate navigating the list. It is useful for sighted users though.
Oh I understand now - you mean on change of the active quick pick item, reveal the line and on enter, focus that line (as it already does)
Yep
To verify, in a terminal with shell integration, run some commands. to enter the accessible buffer. to . Without pressing , use the arrow keys to go between the options. It should scroll to the command if it is outside of the viewport.
Works but I opened
