[seppo0010]

In lists navigate with j/k and vote with a/z.

Hi! I like it, thank you for your contribution :)

p.s. I'm trying to implement the new stuff, especially related to karma, in a way that is easy to enable/disable them, please if you can add something like a KeyboardNavigation constant to app_conf.rb so that it is possible to switch this on/off as needed.

@antirez let me know if there's something you don't like about the pull request to adjust.

Merged! Thank you, great work.

IMHO only two things that can be improved are:

• show help on '?'
• on comments for some reason the 'selection' box is smaller than the comment itself. Probably related to some HTML bug in the code itself?

@antirez
what do you think about adding shortcuts to browse each section?
e.g.: g then t opens top, g then l opens latest.

That's widely used in google reader and seems comfortable for me.

@seppo0010 Merged your fixes, everything works flawlessly now, thanks! :)

Adding shortcuts to browse each section sounds like a great idea, not sure what @antirez thinks about it?
