To a sighted user, there are effectively two sides. The left side is a large
grid of numbers. Each ‘cell’ in the grid is a two ‘digit’ hex number which
corresponds to a single 16-bit unit from the binary file. On the right side is
an ascii representation of the same. The caret is on one side or the other and
the matching unit has a placeholder highlight. Pressing <TAB> will toggle which
side you’re on.
Typing while on the left side will replace the value in whichever cell you’re
on and should only accept hexadecimal values (0-9,a-f). Typing on the right
side will replace the current character with whatever is typed.
What I DON’T know is how all of this works with a screen reader. To be fair, I
find using a binary editor to be fairly niche, and in my years in the industry,
I’ve never had to use one. But, I know that my type of application development
has been fairly specialized (even before coming to Microsoft).

Well I never knew that binary editor was there. I just tried it and it seems a
bit unclear. I am not seeing what I see in my other hex editor which is sets
of hex digits that I can edit like a text file for example in my editor I see:
4D 0E 4B … … … …
Etc…
In visual studio professional I see

The reason why I ask… there is a binary editor in Visual Studio, and I’m not
actually sure of the how accessible it is. Simply put, if it *IS* accessible,
then I’m not particularly concerned. If it’s not accessible, I’d love feedback
on the “Must fix” and “nice to haves”.
If we’re going to break into it to address accessibility issues, I’d like to
know what we could do with it.

Hex and binary editing does happen a lot in malware research and exploitation
development in the cybersecurity side of things, and I know very few tools that
do it well. In fact, I had not heard of frhed, will give that a look

Editing binary files is extremely uncommon for me, and VS works well
enough when I do. Usually for viewing I use the *nix hexdump -C in a
regular console, piped through less.

Hi,
Frhed is what I use. It's a little odd but once you get used to it you
can edit things pretty easily with it.
Cheers.

Out of curiosity, do folks find themselves needing to edit binary files
very often? If so, what tools do you use?
