我可以在 OS X 中启用鼠标中键拖动滚动吗？

我有一个有三个按钮但没有滚轮的鼠标。

在 OS X 中，有没有什么方法（也许使用插件软件）可以让我通过按住第三个按钮并移动鼠标来使用它进行滚动？

我做了锤子勺使用受此线程启发的以下配置脚本：https://github.com/tekezo/Karabiner/issues/814#issuecomment-337643019

脚步：

  • 安装 Hammerspoon
  • 点击其菜单图标并选择Open Config

  • 将以下lua脚本粘贴到配置中：

    -- HANDLE SCROLLING WITH MOUSE BUTTON PRESSED
local scrollMouseButton = 2
local deferred = false

overrideOtherMouseDown = hs.eventtap.new({ hs.eventtap.event.types.otherMouseDown }, function(e)
    -- print("down")
    local pressedMouseButton = e:getProperty(hs.eventtap.event.properties['mouseEventButtonNumber'])
    if scrollMouseButton == pressedMouseButton 
        then 
            deferred = true
            return true
        end
end)

overrideOtherMouseUp = hs.eventtap.new({ hs.eventtap.event.types.otherMouseUp }, function(e)
    -- print("up")
    local pressedMouseButton = e:getProperty(hs.eventtap.event.properties['mouseEventButtonNumber'])
    if scrollMouseButton == pressedMouseButton 
        then 
            if (deferred) then
                overrideOtherMouseDown:stop()
                overrideOtherMouseUp:stop()
                hs.eventtap.otherClick(e:location(), pressedMouseButton)
                overrideOtherMouseDown:start()
                overrideOtherMouseUp:start()
                return true
            end
            return false
        end
        return false
end)

local oldmousepos = {}
local scrollmult = -4   -- negative multiplier makes mouse work like traditional scrollwheel

dragOtherToScroll = hs.eventtap.new({ hs.eventtap.event.types.otherMouseDragged }, function(e)
    local pressedMouseButton = e:getProperty(hs.eventtap.event.properties['mouseEventButtonNumber'])
    -- print ("pressed mouse " .. pressedMouseButton)
    if scrollMouseButton == pressedMouseButton 
        then 
            -- print("scroll");
            deferred = false
            oldmousepos = hs.mouse.getAbsolutePosition()    
            local dx = e:getProperty(hs.eventtap.event.properties['mouseEventDeltaX'])
            local dy = e:getProperty(hs.eventtap.event.properties['mouseEventDeltaY'])
            local scroll = hs.eventtap.event.newScrollEvent({-dx * scrollmult, dy * scrollmult},{},'pixel')
            -- put the mouse back
            hs.mouse.setAbsolutePosition(oldmousepos)
            return true, {scroll}
        else 
            return false, {}
        end 
end)

overrideOtherMouseDown:start()
overrideOtherMouseUp:start()
dragOtherToScroll:start()

智能滚动它的“抓取滚动”功能可以满足您的需求。将其分配给“按钮 3（中间）”，在浏览器（Chrome）、终端、Adobe Photoshop 和 Finder 等应用中，拖动两个轴即可 - 我尝试过的所有应用都无法使用它（使用 4.0 及以上版本的测试版）。它有免费试用版。

轻抚除其他外，它还能做这些事情。（我是开发人员）

它与其他建议的不同之处在于，它能够在每个 Mac 应用程序中使用它，同时仍能识别链接。（以防您使用中键拖动来抓取和抛出，但仍然希望中键单击充当中键）

使用 Smooze 更像是抓取-拖拽-抛出，而不是抓取-拖拽。释放会影响滚动的动量和动画，类似于 iPhone 滚动。

+1 表示锤子勺和一个脚本，一个普通的鼠标/轨迹球让我在 Mac 上抓狂。

我编写了一个在按下鼠标中键时滚动的程序 - 鼠标移动得越远，滚动的速度就越快。

点击仍然像正常点击一样工作，具有 5 像素的死区，因此您不必在按下和释放滚轮之间保持鼠标完全静止。
