This macro formats a paragraph in block mode by filling the spaces.
If nothing is selected, the macro selects the current paragraph (until it finds an empty line). You can format parts of a paragraph by selecting the lines before invoking the macro. Formatting more than one paragraph at once will concatenate them. If at least the first line is indented, the paragraph will be aligned according to this indentation, so that the right margin is in correspondence with unaligned paragraphs (this paragraph is an example).
Put the macro in a folder (preferably %b\Macros\text\) and assign a shortcut to it if you want (e.g. CTRL-ALT-Enter).
At the end of the macro file you'll find another macro that allows you to change the line length through a menu item.
