### Bug fixes

Make it possible for `selectParentSyntax` to jump out of or into a syntax tree overlay.

Make Cmd-Backspace and Cmd-Delete on macOS delete to the next line wrap point, not the start/end of the line.

### New features

The new `deleteLineBoundaryForward` and `deleteLineBoundaryBackward` commands delete to the start/end of the line or the next line wrapping point.
