As explained on the splashscreen, they've remapped that to backslash. I suspect it'd be much more useful with a BT keyboard - lack of ctrl and tab for a start.

The font is pretty ugly too - I can't easily tell the difference between q and g.

However, it is a neat hack, if not very usable.

This commit [1] seems to indicate that it's possible to change the font.

However, I can't actually figure out a way to do so; ":set guifont" doesn't appear to work.

Hi :-) I added font support pretty much at the last minute. Here's an example of something that should work ":set guifont=Courier:h14"

It doesn't seem retina optimized. The font is horrendous on my iPhone 4.

Actually it is (or it should be. Just file a bug if it doesn't work for you). By default anti-aliasing is disabled, but you can toggle it on.

They remapped backslash to esc. Kind of a pain since you have to go through 2 keyboards to get to it, but it works.

How are you supposed to code without backslashes? Are they anticipating never needing to escape anything?

How exactly would going through 2 keyboards to switch modes work in a practical situation?

That's why you'd edit .vimrc to rebind the functionality provided by escape to 'jj' or 'jk' or something of the nature.

The correct way to do it is to attach a toolbar to the top of the keyboard that contains any special keys or commands that one needs, such as "Esc".

This would be awesome for vim. Not just for the escape key, but also for other often used keys. I love the virtual keyboard in Codea for example.
