When you are finished typing, click the check mark in the options bar. To cancel, click the X mark in the options bar. When you use the Type tool, a new Type layer is automatically created. So long as your type is on a Type layer it is editable. Layers and Special Effects Images in Adobe Photoshop are made up of layers.
Layers are very useful for editing images and creating special effects.
For example, you could make a copy of a layer and make some changes to it. If you don't like the results, you can delete the layer and still have your original layer as a backup. You can also combine images by putting different content on different layers. To see the Layers in your image, choose Show Layers from the Window menu. The first colum of the layers palette shows which layers are currently visible.
