Delphi全局热键：

unit Unit1;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants,
  System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs,
  Vcl.StdCtrls, Vcl.ComCtrls;

type
  TForm1 = class(TForm)
    RichEdit1: TRichEdit;
    procedure FormCreate(Sender: TObject);
    procedure hotykey(var msg: TMessage); message WM_HOTKEY;
    procedure FormDestroy(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  id1, id2, id3, id4: Integer;         //id1 ctrl+shift+v , id2 ctrl+shift+window+v

implementation

{$R *.dfm}

procedure TForm1.FormDestroy(Sender: TObject);
begin
  UnRegisterHotKey(handle, id1);            //ctrl+shift+V
  UnRegisterHotKey(handle, id2);            //ctrl+shift+window+V
  UnRegisterHotKey(handle, id3);           //ctrl+shift+Alt+Window+V
  UnRegisterHotKey(handle, id4);         //Window+S
end;

procedure TForm1.hotykey(var msg: TMessage);   //定义下面这种热键，要先写长的判断，不然没有反应！这就是原因！
begin
  if (GetAsyncKeyState(VK_CONTROL) < 0) and (GetAsyncKeyState(VK_SHIFT) < 0) and (GetAsyncKeyState(VK_MENU) and (GetAsyncKeyState(VK_LWIN) and (GetAsyncKeyState(Ord('V')))) < 0) then        //Ctrl+Shift+Alt+Window+V
    ShowMessage('Ctrl+Shift+Alt+Window+V');

  if (GetAsyncKeyState(VK_CONTROL) < 0) and (GetAsyncKeyState(VK_SHIFT) < 0) and (GetAsyncKeyState(VK_LWIN) and (GetAsyncKeyState(Ord('V'))) < 0) then        //Ctrl+Shift+Window+V
    ShowMessage('Ctrl+Shift+Window+V');

  if (GetAsyncKeyState(VK_LWIN) and (GetAsyncKeyState(Ord('S'))) < 0) then        //Window+V
    ShowMessage('Window+S');


//if (msg.LParamLo = MOD_CONTROL) and (msg.LParamHi = 86) then
  if (GetAsyncKeyState(VK_CONTROL) < 0) and (GetAsyncKeyState(VK_SHIFT) < 0) and (GetAsyncKeyState(Ord('V')) < 0) then          //ctrl+shift+v
  begin
    ShowMessage('ctrl+shift+v');
    RichEdit1.PasteFromClipboard;
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);        //另外 hotkey1 hotkey2 hotkey3要写三个
begin
  id1 := GlobalAddAtom('hotkey1');
  RegisterHotKey(handle, id1, MOD_CONTROL + MOD_SHIFT, 86);                          //ctrl+shift+V 成功了~~

  id2 := GlobalAddAtom('hotkey2');
  RegisterHotKey(handle, id2, MOD_CONTROL + MOD_SHIFT + MOD_WIN, 86);                //ctrl+shift+window+V 成功了~~

  id3 := GlobalAddAtom('hotkey3');
  RegisterHotKey(handle, id3, MOD_CONTROL + MOD_SHIFT + MOD_ALT + MOD_WIN, 86);      //ctrl+shift+Alt+Window+V 成功了~~

  id4 := GlobalAddAtom('hotkey4');
  RegisterHotKey(handle, id4, MOD_WIN, 83);      //Window+V
end;

end.

我不会这个编程，但是也过来支持一下

不用控件实现全局热键，good
