[FEATURE] Configure keyboard shortcuts for faster typing of recurring strings

[larcado]

Problem / Use Case
There are occasional instances where you have to type the same thing repeatedly. For example, username/email address for logins.

Proposed Solution
I would like to be able to preconfigure such strings in the settings.

Consisting of:

1. The string (e.g., "my.email@domain.com")

2. The shortcut (e.g., "my.em")

And when I type "my.em" followed by a space on the keyboard, the text "my.em" is changed to "my.email@domain.com".

Please don't limit to single words. A shortcut for typing multiple words at once would also be welcome.
