I wish we hadn't used all the keys on the keyboard.

It is formatted, and I'm tired of using vi. I get really bored.
The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands.
I think one of the interesting things is that vi is really a mode-based editor.
The point is that you want to have a system that is responsive.
Well, limbo is not a good place to be.
I think the hard thing about all these tools is that it takes a fair amount of effort to become proficient.
I think editors have to come out of a certain kind of community.
I just don't like to lose what's in the window.
I remember right after Carter got elected, I was sitting in my apartment in Albany, CA, on a Saturday listening to people call Carter and ask stupid questions while I designed the screen editor.
I think the Macintosh proves that everyone can have a bitmapped display.
I had almost rewritten all of the display code for windows, and that was when I gave up.
But with Interleaf I don't even have a spell program.
I started to write a new editor not too long ago and had it about half done after two days.
But no, I don't generally have trouble with spelling mistakes.
Interleaf is very nice. I expect there to be a lot of competition for programs like that.
The reason I use ed is that I don't want to lose what's on the screen.
So Chuck and I looked at that and we hacked on em for a while, and eventually we ripped the stuff out of em and put some of it into what was then called en, which was really ed with some em features.
Document preparation systems will also require large screen displays.
I think multiple levels of undo would be wonderful, too.
Bitmap display is media compatible with dot matrix or laser printers.
I think it killed the performance on a lot of the systems in the Labs for years because everyone had their own copy of it, but it wasn't being shared, and so they wasted huge amounts of memory back when memory was expensive.
Interleaf is based on the formatting process.
I was surprised about vi going in, though, I didn't know it was in System V.
I got tired of people complaining that it was too hard to use UNIX because the editor was too complicated.
I think the wonderful thing about vi is that it has such a good market share because we gave it away.
That lack of programmability is probably what ultimately will doom vi. It can't extend its domain.
Systems are going to get a lot more sophisticated.
