The vertices are deleted from the line—or polygon—and the feature is
reshaped.
Tip
Undoing or canceling your edits: Use the Undo tool to go
back a step to the previously captured vertex or use the Cancel Edits tool
to erase all edits. These tools are only enabled prior to tapping the
Proceed button. Once you tap the Proceed button and tap ok on the Feature
Properties dialog box, your edits cannot be undone.
