Actually, it's even easier: Create a math inset: Insert->Math->Display formula Type: B=\cases<space>1<right arrow>\textrm<space>if <Insert->Math->Inline formula>x>0<right arrow><right arrow><cntl-enter><down arrow><left arrow>0<right arrow>\textrm<space>if <Insert->Math->Inline formula>x=0<Esc> Looks horrible, but really it isn't! -- Angus
