Add dedicated URL/Email key

[FineFindus]

Is your feature request related to a problem? Please describe.

When typing URLs or entering email addresses, the user often has to type the same ending (e.g. '.com' or '@proton.me').

Describe the solution you'd like

Add a new dedicated key to automatically type out these endings. It could be similar to the emoji key, or how the comma key is replaced with '@' and '/' when entering one of the special input modes.

Use case

This can be a useful feature for saving time, especially when often entering URLs or Emails
