Question

I need a Rebind script for a drag lock feature. The script should allow me to click a button once to start dragging (mouse button down), and click it again to stop dragging (mouse button up).

Rebind AI

lua

-- rebind: min_sdk=0.1.0
-- rebind: name=Drag Lock

local cfg = UI.Schema({
    enabled = UI.Toggle(true, { label = "Enable" }),
    toggle_key = UI.Keybind("Mouse3", { label = "Drag Lock Key" }),
})

local dragging = false

function OnDown(key)
    if not cfg.enabled or key ~= cfg.toggle_key then
        return true
    end

    if dragging then
        -- Release drag
        HID.Up("Mouse1")
        dragging = false
        UI.Notify("Drag released", "info")
    else
        -- Start drag
        HID.Down("Mouse1")
        dragging = true
        UI.Notify("Drag locked", "info")
    end

    return false
end

function OnBlur()
    if dragging then
        HID.Up("Mouse1")
        dragging = false
    end
end

function OnStop()
    if dragging then
        HID.Up("Mouse1")
    end
end

How it works:

Click the toggle key (default Mouse3) once to lock Mouse1 in the down state
Move your mouse while dragging is locked
Click the toggle key again to release the drag
If you switch windows while dragging, the script automatically releases the button in OnBlur

Customization:

Change toggle_key to any key you want (e.g., F8, LAlt, Mouse4)
Disable the feature temporarily with the enabled toggle

This is useful for accessibility, one-handed workflows, or situations where holding a button is difficult or inconvenient.
