Once you have created an internal sequence as a part of a graph, you have it in your graph, but you may want to convert it into external (shared) sequence. Thus, you would be able to use the same sequence for more graphs (when more graphs share it).

You can externalize any internal sequence item into an external (shared) file by right-clicking an internal sequence item in the Outline pane and selecting Externalize sequence from the context menu. After doing that, a new wizard will open in which a list of projects of your workspace can be seen and the seq folder of the corresponding project will be offered as the location for this new external (shared) sequence file. If you want (a file with the same name may already exist), you can change the suggested name of the sequence file. Then you can click OK.

After that, the internal sequence item disappears from the Outline pane Sequences group, but, at the same location, there appears, already linked, the newly created external (shared) sequence file. The same sequence file appears in the seq folder of the selected project and it can be seen in the Navigator pane.

You can even externalize multiple internal sequence items at once. To do this, select them in the Outline pane and, after right-click, select Externalize sequence from the context menu. After doing that, a new wizard will open in which a seq folder of the corresponding projects of your workspace can be seen and it will be offered as the location for this new external (shared) sequence file. If you want (a file with the same name may already exist), you can change the suggested name of the sequence file. Then you can to click OK.

After that, the selected internal sequence items disappear from the Outline pane's' Sequences group, but, at the same location, there appears, already linked, the newly created external (shared) sequence file. The same sequence file appears in the selected project and it can be seen in the Navigator pane.

You can choose adjacent sequence items when you press Shift and press the Down Cursor or the Up Cursor key. If you want to choose non-adjacent items, use Ctrl+Click at each of the desired sequence items instead.
