Hi Joost,
Within the maths environment of LyX, typing any of the above commands (in
this case \mathbb) creates an inset of that type (i.e. a box within which
everything typed will be in, for example, \mathbb). You then have to place
the cursor within this inset to use the font correctly.
Hoping this helps,
Dan
