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
It indeed works when I type it manually (I must have made a typo). However, the math panel seems to be broken for this symbol. Can you try to reproduce that?
