First, read the English article below.

Click the "Color 1" box, then click the color you want to use. It's at the top of the window. Find the place on your canvas in which you want to place the text, then click the place in question. You should see a dotted line indicating a text box appear. In the "Font" section of the toolbar, click the top text box and then click the font you want to use in the resulting drop-down menu. Click the number below the font name, then click the number you want to use for your font. If you want to bold, italicize, and/or underline your text, click the B, I, and/or U button(s) in the "Font" section of the toolbar. Since you adjusted the default font and size, you may need to enlarge the text box. You can do this by placing your mouse cursor over one of the corners of the text box and then dragging diagonally away from the text box's center. In the text box, type in the text that you want to display. If you don't want your text to sit on whatever background items are on your canvas, click Opaque in the "Background" section of the toolbar. Your text's background will be the secondary color listed in the "Color 2" box. When you're done editing your text, click anywhere on the canvas (or outside of it) to anchor the text. Once text has been anchored, you can't move it.
