The Text tool can be found on the Toolbar on the left side of the interface as the "T" icon. With the Text tool active, you can click anywhere on the canvas to create a text layer and add type to your project.
You can adjust Text layer properties in the Inspector in the layer's properties panel. Going from top-to-bottom on the properties panel, below are the descriptions of each parameter:
Font Family- Use this parameter to select the Google Font you'd like to use on the text layer
Font Style- Use this parameter to select the font style you'd like the text layer to have
Tracking/Kerning- Use this parameter to control the space between characters on the text layer
Custom Font Library- Use this feature to upload a font family outside of the google font library.
Font Size- Use this parameter to control the font size of the text layer. Fable's Font Size parameter uses points as its unit.
Line Height/Leading- Use this parameter to control the space between lines on the text layer
Vertical Alignment- Use this parameter to control the alignment of the text layer in relation to its bounding box
Color- Use this parameter to control the font color of the text layer
Color Opacity- Use this parameter to control the font colors opacity
Content/Text- Use this parameter to procedurally populate the text layer
Just like any other layer, you can scale a text layer by clicking and dragging the white squares at the corners of the layer or the blue borders around the layer. However, if you'd like to resize the bounding box of the text layer, you can click and drag the circles positioned on each of the layer's borders.
