# Buttons, keys and locks Button and key latency, native and injected presses held together, locks on native input, and clicks and typing timed by the box. ## Button and key latency Injected left button and 'a' key, timed on the PC's USB bus from the command to the clone's report. The mouse was still, moving every millisecond, or moving while the box also injected a move every millisecond. #### Left button latency, p50 Stock `km.left`Medius `INJECT` | Load and edge | Stock`km.left` | Medius`INJECT` | Result | | --- | --- | --- | --- | | Mouse still, press | 0.723 ms | 0.803 ms | Stock | | Mouse still, release | 0.867 ms | 0.725 ms | Medius | | Mouse moving, press | 8.56 ms | 1.39 ms | Medius | | Mouse moving, release | 8.59 ms | 1.31 ms | Medius | | Mouse moving, box injecting, press | 8.63 ms | 1.02 ms | Medius | | Mouse moving, box injecting, release | 8.68 ms | 0.867 ms | Medius | #### Key latency, p50 Stock `km.down`Medius `INJECT` | Load and edge | Stock`km.down` | Medius`INJECT` | Result | | --- | --- | --- | --- | | Mouse still, down | 1.24 ms | 0.862 ms | Medius | | Mouse still, up | 1.23 ms | 0.867 ms | Medius | | Mouse moving, down | 1.26 ms | 0.974 ms | Medius | | Mouse moving, up | 1.3 ms | 0.978 ms | Medius | | Mouse moving, box injecting, down | 1.67 ms | 0.972 ms | Medius | | Mouse moving, box injecting, up | 1.86 ms | 0.783 ms | Medius | ## Native and injected presses A native key or button held while each box injected another key, or injected a release or click of that same button. #### Native press after the injection | Case | Stock | Medius | Result | | --- | --- | --- | --- | | Native Q held, box injects A | Still held | Still held | Equal | | Native left held, box injects a left release | Still held | Still held | Equal | | Native left held, box injects a left click | Still held | Still held | Equal | ## Locks Each box held a lock for 10 s against native motion and clicks. On the PC's USB bus, a lock is timed from the command to the last native input through, an unlock to the first one back. #### Native input reaching the PC | Lock | Stock | Medius | Result | | --- | --- | --- | --- | | X locked, box idle | None | None | Equal | | X locked, box injecting Y at 1 kHz | None | None | Equal | | X locked, box injecting Y at 125 Hz | None | None | Equal | | X locked, box injecting -1 X at 1 kHz | None | None | Equal | | Left button locked, box idle | None | None | Equal | | Left button locked, box injecting Y at 1 kHz | None | None | Equal | #### Injected press reaching the PC | Lock | Stock | Medius | Result | | --- | --- | --- | --- | | Left button locked | Arrives | Arrives | Equal | #### Lock on X taking effect, p50 Stock `km.lock_mx`Medius `LOCK` | Lock | Stock`km.lock_mx` | Medius`LOCK` | Result | | --- | --- | --- | --- | | Native X motion every millisecond | 3.33-5.62 ms | 0.333-0.471 ms | Medius | #### Lock on X lifting, p50 Stock `km.lock_mx`Medius `LOCK` | Lock | Stock`km.lock_mx` | Medius`LOCK` | Result | | --- | --- | --- | --- | | Native X motion every millisecond | 4.33-6.41 ms | 1.20-1.29 ms | Medius | #### Native input still reaching the PC after the lock, p50 | Lock | Stock | Medius | Result | | --- | --- | --- | --- | | Y, moving every millisecond | 6.45 ms | 0.336 ms | Medius | | Positive Y only, moving +1 and -1 | 5.9 ms | 0.363 ms | Medius | | Wheel, every 10 ms | 0 ms | 0 ms | Equal | | Right button, 50 ms clicksMedius lets a press already under way finish before the lock blocks the button.
