Standard keystrokes and mouse support! On the console, without X!
Either of those alone would be enough, but both together is a killer combination.

But even if you do that, in basically all other existing Linux console editors, from Vim to Nano to Joe to Pico or whatever, your mouse doesn't work because they don't understand mice.
Tilde does.
I never tried ee, though, so I have no idea how it compares or if anyone uses it.
That's the thing. Everyone still things it's OK on xNix to just invent your own keystrokes. It is not OK. There has been a standard for over one-third of a century now and every mainstream OS, including most Linux GUIs, follows it.

I think that these days people just don't know how to operate a GUI with a keyboard, which is why so many Linux GUIs are inaccessible to blind users.
If you can't see, you can't use a mouse. You can't see where it's going.
But computers are extremely valuable to blind users: they can read for you.
By ignoring keyboard access, FOSS OSes are excluding blind users, who could be among their most valuable and passionate supporters... because blind people tend not to be rich and tend not to have much disposable income.
