Long press: accents and symbols

Hold a key and a row of alternatives opens above it. Slide your finger to the one you want and lift. The first one is selected already, so hold and lift gives it at once.

• Letters: first the symbol printed in the key’s corner (% \ | = [ ] < > { } on the top row, then @ # $ _ & - + ( ) on the middle row and * " ' : ; ! ? on the bottom one, as on Gboard), then the accented forms of the letter, the Romanian ones first: ă â on a, î on i, ș on s, ț on t. With shift on, the accents come out as capitals.
• The period key right of space: the usual punctuation, @ " ' _ - ? ! ; / : , and the period. The comma is selected first, the period one step to the right.
• Digits: superscripts and fractions, ¹ ½ ⅓ ¼ on 1, ² ⅔ on 2, and so on; the degree sign on 0.
• Hyphen: en dash, em dash, bullet. Dollar: € £ ¥ ₩ ₽. Quotes: the curly and the German and French ones. ? and !: their upside-down forms.

On the number pads a held key simply types once, so a slow tap on a PIN never opens a row of alternatives. The one exception is the decimal point, whose long press gives a comma.

Long press delay in Settings sets it, from 50 to 550 ms in steps of 50; the default is 200 ms. Shorter opens the row sooner; longer leaves more room for a slow tap.
