Stop at Line Boundaries

Prevents the Left and Right Arrow keys from crossing real line breaks.

Features

• → stops at the end of the current line.
• ← stops at the beginning of the current line.
• Prevents accidental movement into adjacent lines.
• Supports multiple cursors.
• Selection collapsing behaves like normal arrow keys.

Example

Instead of:

abc| ↓

abc |

The cursor stays at:

abc|

And:

|abc ↓

| abc

becomes:

|abc
