Help* How to dash the player for Android

[twistedMind]

Anyone know how to activate "TriggerDash" command that function when you hold-press a certain button (from the image I shown with the red arrow). I know that you can just turn ON "Always dashing" from the menu, but I want the player to run (dash) only when you hold-press a running button. As for now, I can move the player with normal speed using the movement button at the bottom left. However, when I press the running button together with movement button, the player still move with normal speed (no running or dashing). Btw, I use Yanfly Picture Common Event.
