Ctrl+a is bound to SelectAll in Windows mode because that's what people would expect, and it works correctly on Windows.

On Linux, it is selecting everything, but you don't see the selection (you can verify by typing Delete), so I suppose I'm using a VT escape sequence incorrectly.

I was able to change it before (v1.x) with

Set-PSReadlineKeyHandler -Functio BeginningOfLine -Chord "Ctrl+A"
Set-PSReadlineKeyHandler -Functio EndOfLine -Chord "Ctrl+E"

I cannot do it anymore.

Try Ctrl+a (lower case).

whooo, ok it definitely used to work with capital A for whatever reason (I have this line in profile for ages).

[lzybkr]

I know.

It's a side effect of my attempt at better supporting non-English keyboard layouts plus better supporting custom bindings on Linux/Mac using the (mostly) same code as Windows.

Going through old issues.
The only remaining issue is the VT sequence for selection on Linux/macOS. I will close this one in favor of #1411
