is it possible to preview sentence in Glyphs, horizontally or vertically? thanks

Click the Vertical Writing Direction button in the bottom right of Edit View:

how to input the sentence, just like what we do in text editor, but not selecting them. thanks.

You should be able to type the characters for the glyphs just like in any other application. Or insert glyphs by name or Unicode code point with Command-F. See the Handbook section 4.9, Entering Text.

nice. thank you very much
