Weird little bug in 7.0.21. Not sure if it applies to 8.
Type several paragraphs with empty lines between them.
In the last paragraph include the “&” symbol such as with the statement “As shown in in images 7 & 8".
Press Command + A to select all.
The last sparagraph will not be selected and highlighted in light blue. Remove “&” from last sentence and now Command + A selects all.
On the other hand if you add a additional paragraphs after the one with “&” and hit Command + A then paragraph with “&” will be selected but no paragraphs after it.
