* Expose unicode_saved_mods * Add UNICODEMAP shift pair functionality and XS keycode * Add XS to keycode reference documentation * Pick pair index based on both Shift and Caps Lock state * Add XS to Unicode feature docs * Clean up process_unicode* headers * Extract unicode_map index calculation into function * Pick pair index as XOR rather than OR of Shift and Caps states * unicode_input_start() has to be called before the unicode_map index is calculated * Replace unicodemap_input_error() with more generic unicode_input_cancel() * Replace register+tap+unregister with tap_code16(LCTL(LSFT(KC_U))) * UNICODE_OSX_KEY → UNICODE_KEY_OSX, UNICODE_WINC_KEY → UNICODE_KEY_WINC * Make keycode range checks more robust * Fix keycode range checks for different input modes * Add UNICODE_KEY_LNX, update docs * QK_UNICODEMAP_SHIFT → QK_UNICODEMAP_PAIR * XS → XP, update docs * Tweak Unicode docs * Use recently added MOD_MASK_SHIFT and IS_HOST_LED_ON helpers * Update Unicode table in docs/keycodes.md * Update Unicode docs per review comments * Replace references to Mac OS X with macOS in Unicode docs * As of v0.9.0, WinCompose supports all possible code points * Expand descriptions in XP docs * Update keycode table and cycling docs * Further expand cycling docs
