Can you document your xmonad keybindings?

Or maybe the config.

I'm trying your xmonad config, and mod-shift-a, mod-shift-s, mod-shift-d don't seem to do anything:

[ ((modMask .|. m, k), focusNthScreen i greedy >> up)
    | (i, k) <- zip [0..] [xK_a, xK_s, xK_d]
    , (m, greedy) <- [(0, False), (shiftMask, True)]
]

mod-shift-a, mod-shift-s, mod-shift-d don't seem to do anything

When greedy is True, focusNthScreen uses greedyView which focuses the target screen's workspace on the current screen—in other words, swaps the two workspaces. Won't do anything at all unless you have more than one screen (xinerama screen, or xrandr output, a bit confusing terminology, I know).

Can you document your xmonad keybindings?

I never really imagined anyone would try to use the whole thing. It's more of a "if someone asks for something I have, I have a URL to point them to". So no, I don't think I'll be able to find time these days to document my config in more detail. Sorry about that. Feel free to ask questions, though.

What about this code?

primes [n] = [n]
primes ns = [ n ++ [p] | n <- ns | p <- "⠁⠃⠇⡇⡏⡟⡿⣿" ++ ['a'..] ]

I compiled your xmonad and didn't see it anywhere in xmobar.

When you tab/group windows together (mod-shift-comma, untab with mod-shift-period), the bottom xmobar will show grouped windows having the same number, but with additional dots:

Anyway, what are you gonna do about Xmobar?
The new version starting from 0.45 drops its support for Xft font in favor of Cairo/Pango, so the font that you currently use won't work.

Well, https://github.com/liskin/dotfiles/blob/home/.fonts/Makefile together with https://github.com/liskin/dotfiles/blob/home/.config/fontconfig/conf.d/70-fixed-otb.conf and system-wide non-disabling of bitmap fonts in fontconfig, makes the Fixed font work just fine in pango. That being said, no doubt the new xmobar will break lots of things, so I'm in no hurry to upgrade. I don't need anything from the new version, and I don't really have a free day/two to fix all the inevitable breakage.
