When typing an email address or URL on your iPhone, you don't have to spell out .com or .net manually — just hold down the period key.

Touch and hold the . key and a small popup appears with common top-level domains. Slide your finger to the one you want — .com, .org, whatever — then let go to insert it.

Where it works

This only activates in fields iOS recognizes as email or URL inputs, like:

• The address bar in Safari
• Email and website fields in Contacts
• The To, CC, and BCC fields in Mail
• Login forms with an email-type field

It won't appear in a regular text field like a Notes document or an iMessage.

Good to know

• The available domains vary by your region — you might see .co.uk, .de, or .fr alongside the standard options
• Adding foreign-language keyboards to your iPhone can unlock even more domain choices
• This has been around since iOS 7, so it works on every modern iPhone and iPad
