Play harmony for current position

As an amateur, I sometimes write simple arrangements. Each time I enter a note, the sound for that note is played. For me it would be very helpful to have a keyboard shortcut that would play all the selected (not muted) instruments at the same vertical position. The only option I've found is the normal playback, and the ability to set a loop range. Often it is beneficial to hear a longer passage, of course, but I still think that a "play current position" feature would be very helpful.
