6) The sixth icon is the Add Text icon. This icon is used the most and has lots of options. Once you click on the icon, you can select the font, change the color as well as the size.
To change the text itself, type it into the box in the upper right where it says 'Enter Text Here'.
To change the font, just click on the drop down arrow next to the font and select another font.
To change the color just click on the square box with the color in it and select another color.
To change the size of the text, just drag the text from one of the small white squares around it.
When Text is selected (confirm by making sure the tiny 8 square white boxes are around the border of your text) the upper bar in the design tool that appears is extremely helpful. The items on the right side will appear when any text or image is selected. You can do the following things with text or images that are selected:
Align your text or image, crop images, there are 'fit' and 'fill' options, you can adjust the Opacity, you can duplicate the image or text, and you can delete the selected items.
One of the most important tools to know is the 'Position' icon (see third photo below, it looks like a down arrow). Once you click on the down arrow icon a pop out box reveals small squares that look like they are layered. If you have a background layer on top of your text and want to move it below the text, you would select the background layer and click on the left icon (black below the white square icon), keep clicking until the background is moved back enough layers so that it is now behind the text. This is how you move image layers 'forward' or 'backwards'. There are 'move back', 'send to back', 'move forward' and 'send to front'.
