Right-click within the position slider, and while holding down the right mouse button, move the cursor. A blue bar appears within the slider. This bar is called a selection. Notice that the audio now loops within this selection. You can use this feature to quickly create a sample within a larger audio file. To extend or trim the selection, right-click in the position slider without dragging, in other words, right-click and immediately release the right mouse button. To remove the selection, right-click just outside of the position slider.
