1 For cross-platform users (macOS and Linux), the combination of buttons that display is dependent in the toolbar setting. For example, some buttons may not be visible if the Tools>Toolbar Display Mode is set to Normal and the Tools>Toolbar Button Label is set to Show Icon and Text. It also depends on whether you are using a Widescreen Layout or a Regular Screen Layout. 2 For cross-platform users, this option is available from a different toolbar or menu.
