### Bug fixes

Prevent native behavior on Ctrl/Cmd-ArrowLeft/ArrowRight bindings, so that browsers with odd bidi behavior won't do the wrong thing at start/end of line.

Cmd-ArrowLeft/Right on macOS now moves the cursor in the direction of the arrow even in right-to-left content.

### New features

The new `cursorLineBoundaryLeft`/`Right` and `selectLineBoundaryLeft`/`Right` commands allow directional motion to line boundaries.
