The easiest way of repeating an event from the history list is to choose it from the History > Items submenu. There may be times, though, when this is inconvenient (the items on the list may be too long to be able to distinguish between them easily, or you might want to repeat an item that occurred more than ten events ago). In such cases, there are three commands which offer an alternative way of choosing items.
Choose History > Previous to perform the previous item in the history list of the tool. This is usually the most recent event you have performed, but may not be (if, for instance, the last action was itself an event that was already on the history list).
Choose History > Next to perform the next item in the history list. This item is not usually available unless the last event you performed involved an item already on the history list.
Note: You can also use the and buttons in the toolbar.
