If you would like to preview the sound of an instrument without selecting it, hold down Command + Options (Mac) and click the instrument (Control + Alt + Click for PC). Conversely, it's possible to select an instrument without previewing its sound by holding down the Shift + Option while clicking (Shift + Alt + Click for PC).
Thanks Henrik! Shift + Alt + click on PC answered my question.
I suggest to add this shortcut combination to chapter "3.4 Drums Tab Header Bar" | "Articulation Menu", because this shortcut is described in a different chapter "3.2 The Drum Kit Graphic Interface". I was not aware of this by reading reading 3.4.
FYI: I tried combinations like Control or Alt or Shift, but Shift + Alt + click is not a common shortcut combination on PC. Anyway, no problem to learn this combination, just my feedback. Thanks again for your help.
