In the screenshot below, how to remove space below text? I simply added a text box using the type tool and I get that extra space bellow the letter "B" that I don't need. I want to remove that space to center the letter within the octogon.
The "extra" room below the baseline is set in the font for descenders. If you really, really don't want it there, convert the letter to outline text. You will no longer be able to edit the character, but there ya go.
