SelectionClick on the text field in the top right corner to make it active, or double click on some text in the document. Then drag a font from Typeface to your document. Typeface changes the font of all the text in the field.
Typeface makes the targeted font automatically available to Letters. The font will be temporarily activated, which means that it will be deactivated when you close Typeface (depending on your Preference settings). This allows you to freely try and switch fonts and you don't have to worry about cleaning up later.
If you want to keep the font persistently activated, you can click on the activation indicator to deactivate the font. Then click it once more to persistently activate the font.
1. Drag and drop a font from Typeface to Letters
When you drag a font to Letters Typeface will check if it has the necessary permission to switch fonts. The following steps guide you through setting these permissions. If you've already given permission the font of the currently selected text in Letters will be changed right away.
2. Allow Typeface to control other apps using Accessibility features
Security restrictions in macOS prevent communication between apps by default. A dialog to request permission will automatically show up. Choose Open System Preferences to view the current settings. Then click the lock icon to make changes and enable the checkbox next to Typeface.app. This will grant Typeface access to switch fonts in Letters.
Giving permission has to be done only once. If you have previously given Typeface access you don't have to give access again and the dialog will not show up.
After following these steps you're ready to switch fonts in Letters. You can freely drag fonts to your documents and Typeface takes care of activation and changing the selected font.
If you aren't able to switch fonts make sure the macOS automation permissions for Typeface are enabled. To see if Typeface is allowed to change fonts in Letters follow these steps:
- Choose the tab
- Choose from the list on the left
- Click the lock icon to unlock changes
- Enable the Letters checkbox underneath
If the checkbox for Typeface is not available in the list add it using the + button.
