跨平台开发之禅

Flutter belongs to product logic. Native belongs to platform boundaries.

能共享的，应当共享。 不能自然共享的，不要强行共享。

UI 默认用 Flutter。 业务逻辑默认用 Dart。

Use (most) macOS style keyboard shortcuts on Windows

Make Windows PC's shortcut act like macOS (Mac OS X)

With this AutoHotKey script, you can use most macOS style shortcuts (eg, cmd+c, cmd+v, ...) on Windows with a standard PC keyboard.

Note that:

1. you shouldn't change the modifier keys mapping with keyboard DIP. This script assumes you use a standard PC keyboard layout, and wish to use shortcuts as if it was a mac keyboard layout.
2. To use cmd + shift + ↑ / ↓ / ← / → (select text between cursor and top / bottom / beginning of line / end of line), You should disable the Between input languages shotcut from Control Panel\Clock, Language, and Region\Language\Advanced settings > Change lanugage bar hot keys due to conflicting.
