Flowing text around shapes

Sometime the text in a text box needs to flow around another shape such as an image or diagram.

You can do this by adjusting the left/right margins of each paragraph in the text box.
See Margins & Indents
A faster approach is to adjust the line width of just those lines affected.

The text (below) needs to run-around the blue rectangle.
Using the Text tool (), select the lines that need to move.
Choose Text->Line Width->Manual
A border is drawn around all the lines affected and the ruler-bar changes to a blue background.
Select the lines again then drag the right-margin marker on the ruler left until you are clear of the blue rectangle.
The text box will reflow but the lines you adjusted will remain shorter than the other lines thus avoiding the blue rectangle.

The fact that a line of text is in manual adjustment mode is not recorded when you save the PDF. If you reload and edit text that was previously reflowed in this way, it will revert to the original paragraph margins and (in this case) overwrite the blue rectangle again.
