With OSM configured, I type a modifier and then within a configurable time window any key press is registered as Mod+Key . A fairly “horizontal” force curve like that of the Keychron K Pro Silver switches slows me down while writing at speed because the keys do not have anything to prevent me from bottoming out hard and losing momentum. I tried low profile keys, the MT3 keycap set, OEM, and the MOA profile (check my Final thoughts on MOA keycaps and spherical tops in general).
