This hint will help you type a little faster:
Instead of tapping “period > space”, just double-tap the space bar. A quick ‘tap tap’ and a period appears, along with the required space.
An alternative to the double-tap: tap ONCE but use two fingers. You get the same result, a period and a space.
And, if you need more spaces (in spite of the one-space rule discussed here), you can do that, too. Just tap the space bar with three, four or even five fingers to get more spaces.
