How does Telex mode work for Vietnamese?

Telex converts digraph sequences to Vietnamese: "aa"→â, "ow"→ơ, "dd"→đ, "s"→sắc (́), "f"→huyền (`), "r"→hỏi (̉), "x"→ngã (̃), "j"→nặng (̣). It's the standard Telex input method used across Vietnam.

How do I type Vietnamese accent marks and diacritics?

In Telex mode: add tones after vowels using s/f/r/x/j/z. For modified vowels: "aa"→â, "ee"→ê, "oo"→ô, "ow"→ơ, "uw"→ư, "aw"→ă. All 7 base vowels with 6 tones are supported.

How do I type the letter đ in Vietnamese?

In Telex mode type "dd" to get đ. On the keyboard grid, click đ directly. This letter (đ — d with stroke) is unique to Vietnamese and not on standard keyboards.
