Change the proximity of text to the baseline

Baseline shift determines how closely text sits above or below its natural baseline, such as with subscript and superscript characters. If there is no baseline shift, the text sits on the baseline. Baseline shifts are measured in pixels.


Baseline Shift option in the Property inspector

 In the Property inspector, drag the Baseline Shift pop-up slider or enter a value in the text box to specify how low or high to place the subscript or superscript text. Enter positive values to create superscript characters or negative values to create subscript characters.
