Some additional basic strokes are listed below. Space: The horizontal line goes from left to right. Period: Write two diagonal strokes starting at the upper left to get a period. Shift*: Changes the usual case of the next letter. Toggle Caps Lock*: Two upward strokes turns Caps Lock on or off. When Caps Lock is on, all strokes interpreted as letters are converted to uppercase, unless shifted. Backspace: Erases the previous character. If done after an introducer stroke (like shift), it "erases" the introducer only, canceling its mode. Return: This is the enter key. Tab: Think of tab as a shifted space. * These introducer strokes have on-screen mode selectors that can be used instead of writing the stroke shown. To use the mode selector, simply tap its button with your stylus. Punctuation and Symbols With Allegro, punctuation and symbols are written in symbol mode. You can turn on symbol mode either by tapping the on-screen button labeled ".?!" or by writing the symbol mode introducer stroke on the writing pad (a diagonal downward stroke that starts in the upper left corner). As a result, punctuation and symbols require at least one additional tap or stroke before you write the symbol's stroke. Some symbols must also be written in shiftmode. For these symbols, two taps or strokes are required before you write the symbol's stroke: both symbol mode and shift mode must be enabled. Shift mode is enabled by tapping the on-screen Shift button or by writing the shift modeintroducer stroke on the writing pad (a vertical stroke that starts at the bottom center). Note that even in Caps Lock mode, shift must be selected explicitly for these symbols. Symbol mode, like shift mode, only applies to one character. After the stroke for the symbol is written, the mode returns to its previous setting.
