Answer 1

您可以使用 AppleScript 浏览菜单项，但这需要几秒钟。

set proc to "TextEdit"
set output to ""
tell application "System Events" to tell process proc
    set frontmost to true
    repeat with m in menu bar items 2 thru -1 of menu bar 1
        set output to output & name of m & linefeed
        repeat with m2 in menu items of menu 1 of m
            try
                set nme to name of m2
                set sc to my getshortcut(proc, m2)
                if nme is not missing value and sc is not missing value then
                    set out to out & "  " & sc & "  " & nme & linefeed
                end if
            end try
            try
                set mi to menu items of menu 1 of m2
                set subout to "  " & name of m2 & linefeed
                set appendsubout to false
                repeat with x in mi
                    try
                        set nme to name of x
                        set sc to my getshortcut(proc, x)
                        if nme is not missing value and sc is not missing value then
                            set subout to subout & "    " & sc & " " & nme & linefeed
                            set appendsubout to true
                        end if
                    end try
                end repeat
                if appendsubout then set output to output & subout
            end try
        end repeat
    end repeat
end tell
