To obtain the _backtick_ required for fixed-spacing text you can use the key combination:
ALT+096 (from the numeric keypad) if you use Windows
Option + `` if you use Mac
ALTgr+' if you use Linux \
The system allows you to define a maximum of two languages used for translations, i.e. it and en. For each language, you can include a maximum of two CTAs, identified respectively as cta_1 which is mandatory and cta_2 which is optional.
In the event that the user has set an unsupported language, such as German, the system will use the app's default language, i.e. **it**. However, if the default language is not defined in the front-matter, the CTAs will not be recognized and displayed.
Two properties are defined for each CTA:
text representing the text that will be displayed in the CTA
action which represents the action that will be triggered on tapping the CTA
Possible actions
For the action, protocols are defined for the creation of routes within the IO app and the interaction with certain features of the operating system of the device in use.
CTA with Link
To obtain a CTA with a link to a site external to IO, as in the case of a normal link, you must use the protocol iohandledlink:// followed by the full Internet address of the destination site, e.g. iohandledlink://https://io.italia.it
You must add the protocol https:// between iohandledlink:// and the site address
Special actions
In order to enrich your messages while facilitating their use by the recipient, IO supports the creation of CTAs capable of
initiating the creation of an SMS to a telephone number: in this case, you must use the syntax iohandledlink://sms:+393211234567 where"+393211234567" is the recipient's number
initiating the creation of an email to an email address: in this case, you must use the syntax iohandledlink://mailto:name.surname@email.com where "name.surname@email.com" is the destination email address
initiating a call to a telephone number: in this case, you must use the syntax iohandledlink://tel:+39061234567 where "+39061234567" is the telephone number to be called
In all cases, the actual sending of the SMS, email or call will take place within the app set up for this purpose in the user's device, subject to confirmation by the user
Please note that these special actions are only available for CTAs: text links activating them are currently not supported
