To reveal the hidden characters you need to press and hold some keys on the device keyboard. The keys that you can be held and expanded include letters N, C, Z, L, S, A, O, I, U, Y and E while symbols include percent (%), apostrophe ('), exclamation point (!), Question mark (?), period (.), Quotes (""), ampersand (&), dash (-) and Dollar sign ($).

The usual way of accessing the quick taps and other symbols is by tapping ?123 (for symbols) or quick tapping of shift key (to capitalize letter).

This will take you quickly to the main QWERTY keyboard.
