I've been using touch pal, but sadly it's taking too much battery and there are too many adverts. One thing it did well was deleting words from what ever I was writing. I could press the backspace button and it would remove a single character. I could essentially drag the backspace left and it would delete an entire word.
Is it possible to delete entire words like this in SwiftKey? Once you get used to doing this it feels very cumbersome to have to delete each character manually.
