h2. Arguments
_textsize_
{indent}Will display the text using text size relative to 1.{indent}
*lle | lri | ule | uri txt* _text_
{indent}Will display text in lower left | lower right | upper left | upper right corner of the screen.{indent}
*cur | ref | min txt* _text_
{indent}Will display text at cursor position | reference point | lower left of grid window. The reference point is set by the [ref] command.{indent}
*let* _text_
