Icons on the toolbar:
The backward icon will undo the last thing you did.
The forward icon will redo the last thing you did.
The B will bold whatever text you highlight.
The U will underline whatever text you highlight.
The I will italicize whatever text you highlight.
The black box will allow you to change the font color of whatever text you highlight.
The link icon will allow you to hyperlink any text you highlight.
And the trash bin will delete the whole text block.
