No way to specify inputs from two devices

[gahisee]

For example,
I want to map (Ctrl key + Middle mouse button) to trigger
the output Ctrl+V.

I have not found a way if it's possible at all.

OK, after much experiments and a little help from CoPilot,
here's my macro in config.json:

"macros": {
    "keystroke_sleep_ms": 10,
    "ctrl_v_macro": {
        "on_key_down": "BTN_MIDDLE",
        "condition": "$Ctrl_L && !$triggered",
        "action": "set(triggered, 1).hold_keys(Ctrl_L+V)"
    },
    "reset_trigger_mouse": {
        "on_key_up": "BTN_MIDDLE",
        "action": "set(triggered, 0)"
    }
}

but when I press Ctrl key and the Middle mouse button,
there's a flurry of outputs. but no Ctrl+V which is I'm expecting!
Please advise as to what I'm doing wrong...

didn't really review this at all, but control-v is paste. Is the flurry of output whatever was in your clipboard?

[gahisee]

Right, that's all i'm trying to do: when both ctrl key and middle mouse button are pushed, trigger the ctrl-v paste action.
input-remapper gui only allows for single device presets.

no, the flurry of outputs is not ctrl-v's. it's so fast it's hard to tell but it opens multiple browser windows, etc. etc.
if you can manage to find working macros to accomplish this, i'd love to see it. though i admit this is not critical but mainly, at this point, technical exercise...

something like this

On Mouse - macro keyboard + mouse
if_eq($foo, 1, hold_keys(Control_R,v), hold_keys(BTN_MIDDLE))

On Keyboard - macro keyboard + mouse
set(foo, 1).hold_keys(space).set(foo, 0)

I press the button I get space, I press the mouse button, I get the mouse button, I press both I get control-V.

        "on_key_down": "BTN_MIDDLE",
        "condition": "$Ctrl_L && !$triggered",

    },
    "reset_trigger_mouse": {
        "on_key_up": "BTN_MIDDLE",
        "action": "set(triggered, 0)"
    }
}

I have never seen this sort of configuration schema. Not the first time that AI tools suggest configurations for input-remapper that don't work.

Remapping from multiple inputs can be implemented. Some work has already been done here: #1068

Other than that, check https://github.com/sezanzeb/input-remapper/blob/main/readme/examples.md#combinations-spanning-multiple-devices out

thanks for your comments. i learned that in practice, it's not so easy to combine key and mouse to create unique triggers. i accomplished what i wanted by using keyboard and trackball separately.

Yeah, I agree. I hope that I'll find the time to continue #1068 eventually, but the next 1-2 months I'm probably going to be quite busy with other stuff. If this is finished, there will be a button to just apply a preset onto all devices at once. And you will be able to make combinations across arbitrary devices.

In fact, this already works. If you install from the custom_gruops branch there is already a suboptimal solution for the ui.

(And your feedback might actually be quite valuable. If you find some time to install it and encounter a bug, just leave some comments on that PR, I'll look at them)
