The Replace Format dialog can be used to set both the format used for the replacement text and the way it is reflowed and aligned after replacement. 

  1. To apply formatting to your text as it is replaced, tick the Apply Style: check-box.
    Then set the required attributes of Font:, Size: and Colour: as you do in the Find Format dialog box. Leaving a value un-checked or as Unchanged means that attribute will not be altered in the replacement text.
  2. Set-up how you would like the text to reflow after replacement. This is important even in the case when you are not altering the text since changing font or font size will require a reflow to go off. This part of the dialog is the same as that described in Reflow & Alignment
