XKB Expansion + Xmonad Build Source

Changes

XKB Remapping (4-level expansion)

• New level 3 symbols: s→$, ö→=, ä→/
• New level 4: parentheses at j/k (Super+Shift)
• Moved Up from level 2 to level 1 (ö) — fixes terminal scroll (bare Up works; Shift+Up doesn't)
• Consolidated docs: README is single source of truth; local.xkb references it
• Switched from keyd: Initial keyd setup failed on FreeBSD; XKB is native X11, works on both Arch + FreeBSD

Documentation

• Unified README table showing all 14 keys × 4 levels
• Added "Lessons learned" section (Shift modifier gotcha)
• dmenu help now reads README directly (50 lines) — updates automatically
• Single comment in local.xkb references README; no duplication

Build Changes

• Merged local(numpad)+local(remaps) → single local section in build-xkb.sh
• Tested on Arch + FreeBSD ✓

Xmonad Build (Arch Linux)

• Build from source required (no pre-built binary)
• Could not use pacman ghc installed ghc-9.12.4-x86_64-alpine3_12-linux-static-int_native.tar.gz
• See XMonad Build Factory for setup
• Note: Haskell environment only needed on build machine, not targets

Testing

• Arch Linux: keymap builds, levels work, dmenu help displays
• FreeBSD: keymap builds, xkbcomp loads
• st terminal: bare Up scrolls; Shift+Up inert (expected)

Files Modified

• dotfiles/xkb/README.md (doc restructure)
• install/build/xkb/symbols/local (4-level expansion)
• install/build/xkb/build-xkb.sh (simplified sed)
• scripts/dmenu-xkb.sh (added help)
• install/README.md (git rebase guidance)

Notes for Review

• Breaking: ö/ä mappings changed (old: :; → new: ⌫↑ + level3/4)
• Non-breaking upgrade path: just rebuild keymap and restart X
• XKB wins over keyd: Native X11 support, portable across Arch + FreeBSD
• Xmonad: Build from source on Arch (see build factory docs)
