 - `Focusable` interface for components that need hardware cursor positioning. Implement `focused: boolean` and emit `CURSOR_MARKER` in render output when focused.
 - `CURSOR_MARKER` constant and `isFocusable()` type guard exported from the package
 - Editor now supports Page Up/Down keys (Fn+Up/Down on MacBook) for scrolling through large content ([#732](https://github.com/badlogic/pi-mono/issues/732))
+- Expanded keymap coverage for terminal compatibility: added support for Home/End keys in tmux, additional modifier combinations, and improved key sequence parsing ([#752](https://github.com/badlogic/pi-mono/pull/752) by [@richardgill](https://github.com/richardgill))
 
 ### Fixed
 
 - Editor no longer corrupts terminal display when text exceeds screen height. Content now scrolls vertically with indicators showing lines above/below the viewport. Max height is 30% of terminal (minimum 5 lines). ([#732](https://github.com/badlogic/pi-mono/issues/732))
 - `visibleWidth()` and `extractAnsiCode()` now handle APC escape sequences (`ESC _ ... BEL`), fixing width calculation and string slicing for strings containing cursor markers
+- SelectList now handles multi-line descriptions by replacing newlines with spaces ([#728](https://github.com/badlogic/pi-mono/pull/728) by [@richardgill](https://github.com/richardgill))
