Summary

NAV (layer 1) changes only; every other layer and behaviour is unchanged.

• NAV S / D are hold-taps (&hml LALT LG(LS(K)), &hml LCTRL LG(LS(L))): tap = the Super+Shift+K/L monitor shortcuts they held before, hold = Alt / Ctrl. NAV + held mod + a right-hand NAV key now works (Alt+PrtSc, Ctrl+Home, Ctrl/Alt+arrows). F already passed Shift through.
• Screenshot column on the inner left edge: Ctrl+PrtSc (T, 18), Alt+PrtSc (G, 31), Shift+PrtSc (B, 44).
• NAV layout otherwise as before: F-keys on top, Home/PgDn/PgUp/End/Ins/PrtSc and HJKL arrows on the right, Super-key workspace/monitor combos on the left and right bottom rows.

Behaviours unchanged: hml/hml_idx/hmr/hmr_idx/ralt_mt timings as in main.

Docs: NAV page, WM_KEYBINDS.md, CLAUDE.md hold-tap table.

Left half only (keymap lives on the central); no settings reset.

Request: NAV was hiding Ctrl/Alt (S/D held Super+Shift+K/L), so Ctrl+PrtSc / Alt+PrtSc were unreachable. Asked for both: mods usable under NAV and dedicated screenshot keys, as a column on the last left column.

Changed (NAV only):

• S (28) &hml LALT LG(LS(K)), D (29) &hml LCTRL LG(LS(L)): tap keeps the monitor shortcut, hold = Alt/Ctrl.
• T/G/B (18/31/44): LC(PSCRN), LA(PSCRN), LS(PSCRN).

Rationale: first draft made S/D &trans and moved the shortcuts to W/E; the owner preferred keeping them on S/D as hold-taps. Trade-offs accepted: shortcut fires on release, and hml's positional list means a held Alt/Ctrl only resolves against right-hand keys (or S/D/F), so e.g. Alt + the screenshot column yields the shortcut — that's why the column carries the mods itself.
