Hard Space will create a space character that cannot break across a line. You will find this especially useful in keeping two or more words under the effect of a flush right command.
Another example of the use of this is where, for ease of reading, you may not want a telephone number to be split over two lines (or even two pages!). e.g.
To insert a Hard Space, place your cursor where you want to have a Hard Space, and press Alt+F2. The result would be as shown below:
This number must not be split over two lines. e.g.
+44 1604 792777.
Note: If using Unified English Braille, using a hard space in this way will add dot 5 in place of the hard spaces.
