Introduces LCK_FN1–LCK_FN4, LCK_CTL, and LCK_BASE custom keycodes that
toggle a layer into a locked state so it stays active after momentary keys
are released. A second press on the same lock key or pressing LCK_BASE
clears all locks and returns to BASE.
Implements rgb_matrix_indicators_advanced_user to colour the ESC key
(LED 0) based on the current layer: dark on BASE, blue on FN1, green
on FN2, orange on FN3, purple on FN4, and red on KEEB_CTL.
Adds a three-key combo (, . /) that fires TO(BASE), providing an
emergency escape hatch when stuck on an unknown layer. COMBO_ONLY_FROM_LAYER
is set to 0 in the keymap config.h so keycodes are always resolved from
BASE, making the combo reliable regardless of the active layer.
Document build commands, code style, and development workflow for the
Q5 Max via keymap. Emphasize that all qmk commands must be run inside
the project Python venv (.venv/bin/activate) rather than the system qmk.
Implement a chord-mode unicode entry system activated by Fn1+LeftAlt
(CHORD_KEY). Supports two activation styles: tap CHORD_KEY then type
the sequence within a 2-second window, or hold CHORD_KEY, type the
sequence, and release to commit.
- Add chord_unicode.c/h with a ~110-entry table covering math symbols
(°²³√≈≠≤≥±÷×∞π), Greek letters, currency, fractions, arrows,
typography, and a broad emoji set
- Prefix-aware matching with a 300ms disambiguation timer handles
same-prefix alias pairs (e.g. lte/lteq→≤, inf/infty→∞) cleanly
- Backspace deletes, Enter confirms, Escape cancels while in chord mode
- Modifier and layer key-up events pass through so TT(FN1) release
correctly deactivates the layer while chord mode is active
- Enable UNICODE_ENABLE and wire chord_unicode.c into the build
Add additional functionality and more intuitive use of existing keys:
- Add a Sleep key (FN1+Esc)
- Add a Power key (FN2+Esc)
- Keep old End key behavior alongside tap-dance (FN1+Home - End)
- Add Home key (FN1+LeftArrow)
- Add End key (FN1+RightArrow)
Replace stock MAC/WIN dual-boot layers with a single-OS 6-layer layout
(BASE, FN1, FN2, FN3, FN4, KEEB_CTL). Add tap-dance Home/End, a mouse
control layer (FN2), and timer-based Alt+Tab cycling on the FN2 encoder.
- Restructure layers: drop MAC_BASE/MAC_FN/WIN_BASE/WIN_FN; add FN1-FN4
and KEEB_CTL with Bluetooth/RGB controls
- Add ALT_TAB_FWD/ALT_TAB_BWD custom keycodes driven by matrix_scan_user
timer to hold Alt across encoder ticks (750ms timeout)
- Assign FN2 encoder to Alt+Tab / Alt+Shift+Tab cycling
- Add TD_HOME_END tap-dance (tap=Home, double=End) on numpad Home key
- Enable MOUSEKEY_ENABLE and TAP_DANCE_ENABLE in rules.mk
- Set DYNAMIC_KEYMAP_LAYER_COUNT=6 and TAPPING_TOGGLE=3 in config.h
