Avoid Hyphenation with Lyx

[Manfred Hainer]

How do I avoid hyphenation of a word which already contains a hyphen?
A word containing a hyphen, like  P-Tracker  should never be hyphenated.
With Tex it is sufficient to write   P"~Tracker   -  which will result in 
P-Tracker on the printed document and it will never be divided at the end of 
a line.
In other words, how to avoid:   P-
Tracker   ?
How do I accomplish this with Lyx?
