“Lowering the actuation depth improved my reaction time in competitive games. Analog mode in racing titles feels surprisingly natural. The mouse glide is smooth.”
“I thought the macro didn't have infinite repetitions, but there are no helpful images anywhere on the internet. I still haven't found the answer.”

Keychron K1 SE vs K2 HE: your questions
The Keychron K2 HE is designed for competitive gaming. It has a 1000 Hz polling rate, magnetic switches with adjustable actuation points, and features like rapid trigger and Last Key Priority that are highlighted by the manufacturer as advantages for fast-paced games.
No. The manufacturer states the K1 SE's hot-swappable sockets are only compatible with low-profile Keychron optical switches and low-profile Gateron mechanical switches. It is explicitly noted as not compatible with any normal profile MX style mechanical switch.
The K2 HE is compatible exclusively with Gateron double-rail magnetic switches. The vendor page specifies it does not support other magnetic switches like the Gateron Magnetic Jade or KS-20 models, and it is not compatible with traditional mechanical switches.
The Keychron K2 HE has a larger 4000mAh battery compared to the K1 SE's 2000mAh. The K2 HE's vendor description claims a wireless working time of up to 110 hours in lab tests, though actual results will vary with usage and lighting.
Yes. Both the K1 SE and K2 HE include keycaps for both Windows and Mac operating systems and have a physical switch to toggle between the systems, as confirmed in their respective product descriptions.
The K2 HE offers extensive reprogramming via open-source QMK firmware and the VIA-compatible Keychron Launcher web app. The K1 SE's description does not mention QMK, VIA, or similar advanced reprogramming software support.
The K2 HE is likely quieter out of the box. Its vendor description details multiple sound-dampening layers including 3.5mm EVA foam, EPDM foam, a silicone pad, and PET film. The K1 SE description does not mention any internal sound-dampening materials.

Yes, both keyboards feature RGB backlighting. The K1 SE offers 18 types of RGB backlit effects. The K2 HE has north-facing RGB LEDs with over 22 backlight modes that are customizable through its web app.
The Keychron K1 SE is more travel-friendly. It is explicitly marketed as "ultra-slim" with low-profile switches, and its TKL (80%) layout is compact. The K2 HE is heavier (over 1.7kg) and has a denser construction with more internal materials.
For the K1 SE, the package includes a keyboard, a USB-A to USB-C cable, a keycap puller, and a user manual. The K2 HE's listed contents are not fully detailed in the provided text, but it is shown as frequently bought with separate keycap sets, palm rests, and cables.
