An E.161 standard modern telephone keypad, as used for text messaging.

A Multitap is also a device that expands the amount of controller ports on a video game console.

Multi-tap refers to a text entry system for mobile phones.The alphabet is printed under each key (beginning on "2") in a three-letter sequence as follows; ABC under 2 key, DEF under 3 key, etc. Notable exceptions are the "7" key, which adds a letter ("PQRS"), and the "9" key which includes "Z." Punctuation is typically accessed via the "1" key and various functions mapped to the "*" key and "#" key.

The system is used by repeatedly pressing the same key to cycle through the letters for that key. For example, pressing the "3" key twice would indicate the letter "E". Pausing for a set period of time will automatically choose the current letter in the cycle, as will pressing a different key. This pause has been called a "ghasp".^[1]

It is commonly used in conjunction with text-messaging services. Some portable telecommunications devices (such as the BlackBerry) have bypassed the need for this by incorporating a mini-keyboard for users to type on. Most standard mobile phones currently do not include that feature, relying on multi-tap or predictive text instead.
