A grid control is a type of list control that allows its items to be edited. The Track view uses a grid control, as do the Channels, Mapping, Modulations, and Step Values bars. To edit an item, left-click it. This causes either a pop-up edit box or a drop list to appear, depending on the data type. If a grid row is selected, you can also edit its first item by pressing Tab. While the pop-up control is displayed, you may edit the value or type a new one. To end your edit, left-click outside of the pop-up control, or press one of the following keys:
| Enter | Saves the edit. |
| Escape | Discards the edit. |
| Tab | Saves the edit and moves to the next column. |
| Shift+Tab | Saves the edit and moves to the previous column. |
| Ctrl+Down | Saves the edit and moves to the next row. |
| Ctrl+Up | Saves the edit and moves to the previous row. |
Selection works the same way as in a list control, with one exception: to select rows via mouse, you must left-click within the primary column, otherwise you'll edit an item instead of selecting. The primary column is usually the leftmost column, unless you've reordered the columns. For example in the Track view, the primary column contains the track numbers, and has a number sign (#) in the column header.
To change an item in multiple rows at once, first select the desired rows, and then edit the item within any one of the selected rows.
