Use iPhone spacebar like a mouse

In a hurry, you type the following on your iPhone text message app: Let me see weatherthis works.

You need to make a separation and change the word weather to whether.

You can use your spacebar as you would a mouse to scroll through the letters. Hold the spacebar down and wait until you feel a vibration or the keyboard goes blank. Now slide your finger along the spacebar and you can move the cursor wherever you need to make a change.
