I would like to increase the font size of the text in a document. To do so, I select the text and choose a desired font size.
I can also type the font size if I like a certain font size. I press Enter afterwards.
Alternatively, I can click on:
Format -> Character... -> Font
I can type or select the size and click on OK.
How about making many documents with a certain font size of the text? I click on:
Format -> Styles and Formatting -> Character Styles
Right-click on Default Style. Select New...
Type a new name for the style. I type "Big".
Click on Font. Change the size. (I type 200.)
Click on OK.
I select the text and double-click on "Big".
I can show or hide the Styles and Formatting window by pressing F11.
I can double-click on the style I created ("Big" style in this case).
