In examples.Sample Outline 2, position the bar cursor on the heading labeled "Subhead 1.1.1" and then execute:
op.deleteSubs ()
» true
Notice that the indented lines under this subhead - labeled "Subhead 1.1.1.1" and "Subhead 1.1.1.1.1" - disappear and the outline re-displays with those lines missing. This operation cannot be undone, so use the "Revert" option in the File menu to reverse
the effect of this change.
In examples.Sample Outline 2, position the bar cursor on the last line, "Subhead 2, Summit," and execute:
op.deleteSubs ()
» true
Nothing happens because the selected line has no subheads.
