How? What code should be entered? Where will I insert the code? Here's my script:

SoundCtrlButton := TNewButton.Create(WizardForm);
SoundCtrlButton.Parent := WizardForm;
SoundCtrlButton.Left := 8;
SoundCtrlButton.Top := WizardForm.ClientHeight - 
  SoundCtrlButton.Height - 8;
SoundCtrlButton.Width := 40;
SoundCtrlButton.Caption :=
  ExpandConstant('{cm:SoundCtrlButtonCaptionSoundOff}');
SoundCtrlButton.OnClick := @SoundCtrlButtonClick;

推荐答案

在Windows控件中，只需在控件标题中的字母前加上&即可将其标记为访问键.

In Windows controls, you just prefix a letter in control caption with & to mark is as an access key.

请参见 https: //docs.microsoft.com/zh-CN/cpp/windows/defining-mnemonics-access-keys#mnemonics-access-keys

SoundCtrlButton.Caption := '&Mute';

或者在您的情况下，通过自定义消息间接进行:

Or in your case, indirectly via a custom message:

[CustomMessages]
SoundCtrlButtonCaptionSoundOff=&Mute

查看在Default.isl中如何定义标准按钮标题:

See how the standard button captions are defined in Default.isl:

ButtonBack=< &Back
ButtonNext=&Next >
ButtonInstall=&Install
