如何用AppleScript设置热键，在Word/Pages打字时后台控制VLC？

VLC Media Player 实现步骤 #

1. 开启VLC的AppleScript支持 #

打开VLC → 偏好设置 → 界面 → 主界面，勾选AppleScript选项，重启VLC生效。

2. 各功能的AppleScript代码 #

直接复制以下代码，配合热键工具（如Spark）使用：

• 播放/暂停

tell application "VLC" to playpause

• 回退5秒

tell application "VLC"
    if exists current item then
        set current time of current item to (current time of current item) - 5
    end if
end tell

• 前进5秒

tell application "VLC"
    if exists current item then
        set current time of current item to (current time of current item) + 5
    end if
end tell

• 快退（慢放，速率0.5x）

tell application "VLC" to set rate to 0.5

如果需要倒放，将代码改为 tell application "VLC" to set rate to -1

• 快进（加速，速率2x）

tell application "VLC" to set rate to 2

3. 用Spark绑定热键 #

打开Spark → 点击「+」新建快捷方式 → 选择「AppleScript」类型 → 粘贴对应代码 → 设置触发热键（例如：播放/暂停用 Cmd+Opt+P，回退5秒用 Cmd+Opt+←）。

QuickTime Player 修正方案 #

你之前的代码问题在于时间单位（QuickTime用毫秒）和命令细节，以下是正确代码：

• 播放/暂停

tell application "QuickTime Player"
    if exists document 1 then
        if playing of document 1 is true then
            pause document 1
        else
            play document 1
        end if
    end if
end tell

• 回退5秒

tell application "QuickTime Player"
    if exists document 1 then
        set current time of document 1 to (current time of document 1) - 5000
    end if
end tell

• 前进5秒

tell application "QuickTime Player"
    if exists document 1 then
        set current time of document 1 to (current time of document 1) + 5000
    end if
end tell

• 快退（慢放0.5x）

tell application "QuickTime Player"
    if exists document 1 then
        set rate of document 1 to 0.5
    end if
end tell

• 快进（加速2x）

tell application "QuickTime Player"
    if exists document 1 then
        set rate of document 1 to 2
    end if
end tell

同样用Spark绑定热键即可，代码中加入了「检查文档是否存在」的判断，避免无视频打开时报错。
