After you give a particular weighting command, you can view a table of weights of all paragraphs.

The first column presents the paragraph number. This is the number that you enter if you use the "Go to" option. The second column indicates the character position at which the paragraph starts, and the third column displays the weight assigned to this paragraph. Note that weights currently cannot be saved.

Double-clicking in the second or third column on the line for a paragraph takes you to the source text window at the beginning of the paragraph selected.

You can invoke a commonly used sequence of weighting commands by using a script.

To create a script automatically from your most recent sequence of weighting decisions, select "Save sequence as..." from the "Weight" menu.
