| 111 | // each mouse-dragged event received, and only for some ammount, |

| 115 | // selection-expanding to commence. Once commenced, it will |
| 116 | // continue to the end of text (provided that mouse-button is |
| 117 | // hold pressed), but it may take hardly predictable ammount of |
| 118 | // time. However, repeatedly dragging mouse seems perfectly help |
| 119 | // here, instead of having to use 'Thread.sleep( ??? )'. |

| 121 | // 1-st drag-event. After 1-st movement, only mouse-exited event |
| 122 | // will be generated. If mouse was released after first movement |
| 123 | // here, we would even get mouse-clicked event (at least for now, |
