2 finger tap is easier than blackslash for input esc

[pinxue]

To input blackslash in iOS, we need switch to symbol keyboard by two click, not a good idea. Personally, I prefer to using two finger tap gesture as an alternative.

I have forked it as https://github.com/pinxue/Vim .

Thanks for the patch @pinxue ! However I won't pull this in, as it isn't user-customizable. Sure backslash isn't the best solution. But at least it's something users can change without rebuilding Vim.

In that case, I think the proper fix would be to solve issue #3 by adding gestures as mappable objects.

Thanks a lot for your time though !
