Sometimes you will want to keep two words together and ensure
that they are never split by a line break. For example, a name such
as RISC OS, or a telephone number, may not make as much sense
to readers if it is broken up over two lines.
The way to do this is to enter a hard space between the words.
To enter a hard space, in RISC OS simply type Alt-space (ASCII
character 160) where you would normally hit the space bar. In
Windows, either type Alt-0160 (using the numeric keypad) or Right Alt-space.
A hard space is treated like an ordinary character and so is
always the same width. If your text is fully justified, the space
between the hard-spaced words will not be stretched to fill the
line out but will remain the standard space.
Hard spaces are underlined; ordinary spaces are not.
