The Gingerbread update to the Droid X added a new multitouch keyboard feature called key-chording. It allows you to quickly use numbers and symbols on the multitouch keyboard. Here's how to use it:
Key-chording is achieved by using the ?123 key as a shift key.
While typing, press the ?123 key and hold it. When the number and symbol key layout displays, without lifting it, drag your finger to the number or symbol you want. Once you've selected the number or symbol, let go. The keyboard will automatically return to letters.
Pretty simple, right? Now you can type away much quicker because you no longer have to pause to enter a number or symbol.
