Google has just launched a new tool called Google Scribe which helps you get autocomplete word suggestions as you type, so that you can save much more time in typing the whole keyword and complete is fast by using the autocomplete suggestions as shown in the image below.
By default when you use this online tool to type text, while typing the word when you wait to type it will auto suggestion words as per the characters you had already typed. You can use the number keys on the keyboard to complete the word more quickly or press up down arrow key to select the right word you were actually thinking of typing.
Note: You can also change the auto type suggestion settings to suggest word when you press tab or don’t suggest at all by clicking the drop down after show suggestions as you can see in the image above.
