## Unreleased
### Added ⭐
* Support a subset of macOS' emacs input field keybindings in `TextEdit` ([#1243](https://github.com/emilk/egui/pull/1243).
* Much improved font selection ([#1154](https://github.com/emilk/egui/pull/1154)):
* You can now select any font size and family using `RichText::size` amd `RichText::family` and the new `FontId`.
* Easily change text styles with `Style::text_styles`.
