RadicalBox

RadicalBox
is a low-level box construct that represents the displayed object in notebook expressions.
  • In a notebook a RadicalBox can be created using Ctrl+@ or Ctrl+2, then using Ctrl+% to move to the index position. Ctrl+Space moves out of the radical.
  • The baseline of RadicalBox is taken to be the baseline of x.
  • If RadicalBox does not fit on a single line, it is output as .
