Using the Cursor
On the top row all the way to the left, you can find the cursor icon. Use this feature to select and highlight objects, move them around, and rotate them.
The cursor button must be selected in order to move objects around.
Creating a Text Box
Just to the right of the cursor button, you'll see a button with a 'T' on it. This will allow you to enter custom text into the diagram.
Click on the 'T' button, then click where you want to place the text box. Once you've clicked, you'll see a small rectangle. Click inside of that box and type what you want to put into the box.
If you want to edit the text later on for some reason, make sure the text button on the row of buttons is selected, then click inside the text box.
Once you're done typing, click the cursor icon and you can move the text box around where you want it.
There are two ways to delete unwanted objects:
