in RE#, we solve this by encoding the context information in the state itself. below, you can see the state machine for the regex ab(?=cd), which matches an ‘ab’ only if it’s followed by a ‘cd’. encoded in the final state, is the information that the match actually happened two characters ago.

Like other models from Keychron, the gasket-mount system is soft and comfortable without being over-the-top, and the spherical keycaps, while a bit tall, feel natural to use even for prolonged typing sessions. The plastic case feels sturdy in hand without being too heavy, and exposed hex screws on the underside look stylish while also making customization (and repairs) easy. Compared to the Q series’ metal case, the V8 has the advantage of flip-out feet to adjust the keyboard’s angle. The keycaps are all fairly standard, meaning you can easily find replacement keycaps (just be sure they have a split spacebar included, or pick a keyset with an add-on spacebar kit), and the switches are hot-swappable as well. The only real downside is that the layout and lighting can’t be customized wirelessly. Instead, you need to disconnect from 2.4 GHz or Bluetooth and connect the keyboard to your device with a USB cable.
