com.apple.symbolichotkeys:AppleSymbolicHotKeys中的第一个parameters值代表什么?

详细信息...

AppleSymbolicHotKeys结构

位于以下位置的OS X符号热键plist文件

~/Library/Preferences/com.apple.symbolichotkeys.plist

将热键存储在名为"AppleSymbolicHotKeys"的字典中，其条目类似于

<action:int> = Dict {
    enabled = <enabled:bool>
    value = Dict {
        type = <type:string>
        parameters = Array {
            <param_1:int>
            <param_2:int>
            <param_3:int>
        }
    }
}

示例:

10 = Dict {
    enabled = true
    value = Dict {
        type = standard
        parameters = Array {
            56
            28
            1572864
        }
    }
}

专业提示:您可以使用

/usr/libexec/PlistBuddy -c "Print :AppleSymbolicHotKeys" ~/Library/Preferences/com.apple.symbolichotkeys.plist

值

action:int

这是热键将执行的操作的ID.网上有相当完整的列表，请进行谷歌搜索，因为我没有足够的积分来发布链接或其他内容.

enabled:bool

是否启用了热键.

type:string

似乎总是标准".

param_1:int

这是我无法获得的.它似乎不一定与参数2和3有关，尽管当其他参数更改时它通常也会更改.例如...

我可以在System Preferences -> Keyboard -> Shortcuts -> Mission Control视图中单击Restore Defaults，它将切换到桌面1"设置为"ctrl + 1".读取该操作的值(数字118)，我看到param_1设置为65535.如果在UI中手动将组合键设置为"ctrl + 1"，则将param_1设置为49. param_2和param_3的值始终保持不变.

param_2:int

这似乎是

的关键代码

/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h

用于按下非修饰键，但值65535在param_1中非常常见，并且在本地计算机上的param_2中显示，用于操作160、163和175. /p>

param_3:int

似乎指示要按下的修改键，根据

MODS = {
  0=>"No modifier",
  131072=>"Shift",
  262144=>"Control",
  524288=>"Option",
  1048576=>"Command",
  393216=>"Shift + Control",
  655360=>"Shift + Option",
  1179648=>"Shift + Command",
  786432=>"Control + Option",
  1310720=>"Control + Command",
  1572864=>"Option + Command",
  917504=>"Shift + Control + Option",
  1441792=>"Shift + Control + Command",
  1703936=>"Shift + Option + Command",
  1835008=>"Control + Option + Command",
  1966080=>"Shift + Control + Option + Command",
}

您会注意到代表多个修饰符的数字是它们代表的修饰符的总和，例如

"Shift + Control" = 393216 = 131072 + 262144 = "Shift" + "Control"

所以...

任何见解将不胜感激，并希望这可以作为我向其他接近该主题的人挖掘的信息的参考.

解决方案

它是键上字母的ASCII码，如果没有ASCII码，则为-1(65535).请注意，字母是小写字母，因此D为100(小写字母d).

有时，通常具有ascii码的键使用65535代替.当使用控制键修饰符(例如与特定空间的热键)一起使用时，似乎会发生这种情况.

what does the first parameters value in com.apple.symbolichotkeys:AppleSymbolicHotKeys represent?

details...

the AppleSymbolicHotKeys structure

the OS X symbolic hotkeys plist file at

~/Library/Preferences/com.apple.symbolichotkeys.plist

stores hotkeys in a dict called as 'AppleSymbolicHotKeys' with entries that look like

<action:int> = Dict {
    enabled = <enabled:bool>
    value = Dict {
        type = <type:string>
        parameters = Array {
            <param_1:int>
            <param_2:int>
            <param_3:int>
        }
    }
}

example:

10 = Dict {
    enabled = true
    value = Dict {
        type = standard
        parameters = Array {
            56
            28
            1572864
        }
    }
}

pro tip: you can take a look with

/usr/libexec/PlistBuddy -c "Print :AppleSymbolicHotKeys" ~/Library/Preferences/com.apple.symbolichotkeys.plist

the values

action:int

this is the id of the action the hotkey will take. there are reasonably complete lists around the net, do some googling 'cause i don't have enough points to post links or whatever.

enabled:bool

whether the hotkey is enabled.

type:string

always seems to be 'standard'.

param_1:int

this is the one i can't get. it doesn't seem necessarily connected to params 2 and 3, though it often changes when the other params are changed. for instance...

i can click Restore Defaults in the System Preferences -> Keyboard -> Shortcuts -> Mission Control view, and it will set "Switch to Desktop 1" to "ctrl + 1". reading the value for that action (number 118), i see that param_1 is set to 65535. if i manually set the key combo to "ctrl + 1" in the UI, i get param_1 set to 49. the values of param_2 and param_3 stay the same throughout.

param_2:int

this seems to be key codes from

/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h

for the non-modifier key to be pressed, except for the value 65535, which is very common in param_1, and shows up in param_2 on my local machine for actions 160, 163 and 175.

param_3:int

seems to indicate the modifier key to be depressed, as according to

MODS = {
  0=>"No modifier",
  131072=>"Shift",
  262144=>"Control",
  524288=>"Option",
  1048576=>"Command",
  393216=>"Shift + Control",
  655360=>"Shift + Option",
  1179648=>"Shift + Command",
  786432=>"Control + Option",
  1310720=>"Control + Command",
  1572864=>"Option + Command",
  917504=>"Shift + Control + Option",
  1441792=>"Shift + Control + Command",
  1703936=>"Shift + Option + Command",
  1835008=>"Control + Option + Command",
  1966080=>"Shift + Control + Option + Command",
}

where you will notice the numbers representing multiple modifiers are the sum of the modifiers they represent, e.g.

"Shift + Control" = 393216 = 131072 + 262144 = "Shift" + "Control"

so...

any insight would be greatly appreciated, and hope this can serve as a reference for the info i dug up to anyone else approaching the subject.

解决方案

It is the ascii code of the letter on the key, or -1 (65535) if there is no ascii code. Note that letters are lowercase, so D is 100 (lowercase d).

Sometimes a key that would normally have an ascii code uses 65535 instead. This appears to happen when the control key modifier is used, for example with hot keys for specific spaces.

There is a nice list of keys and values from 2011 here, along with some other good details:
