Spends time: At the end of a sentence, press the space bar twice to insert a period and a single space.
Faster quote: Anyone whose name includes punctuation (like mine) knows what a hassle it can be simply enter your name. Instead of going to the keyboard the number of punctuation, simply slide the key to insert an apostrophe.
Do the same for citations: time flow / question mark key cites increases.
Simple addition of special keys: Hold a number of other letters from the keyboard to use characters like the French soft C (as a "boy"), the Spanish tilde (like "Manana"), and I, umlaut (as in "naive" ).
Expand your horizons punctuation: You will find a wide selection of punctuation marks using the same technique in the keyboard punctuation. For example, insert an exclamation point upside down question mark or slip up (or holding) the key.
Add ellipses sliding the key (only the number of available punctuation). Insert different currency symbols by clicking the dollar sign, or drag the button to add a symbol of degree zero. Perhaps my favorite of these shortcuts is the ability to add a touch sliding the button on the dash.
