Blueduino is an accessibility tool which simplifies entering often used text by expanding shortcuts.
If a freely adjustable shortcut is detected the app proposes to replace it with the long text.
It supports text macros, e.g. salutations like 'with best regards [name]' and 'kind regards [name]' are automatically prepared with the name and then inserted.
The app contains predefined text modules that can be edited. It works with most e-mail apps, notebooks and messengers.
Multiple expansions for the same shortcut are supported, so it can be chosen between e.g. more formal or intimate greetings.
The Blueduino app is not free, test and try it out for 14 days.
