The guide
What yunit does, and where.
This page goes through every part of yunit, where to find it and what each control does. The numbered marks sit on real screenshots of the extension.
01On the page
On the page
On any page in the language you are learning, while the extension is on.
yunit reads the page and picks a few words, then writes a small translation above each one. The density setting in the popup decides how many words it picks. The page itself is left as it was, and the translations sit above the line.

- A marked word. The translation is written above it, and the dotted line underneath shows that the mark is yunit’s. Resting on it plays the word, and clicking it opens the card.
- A kept word has a solid amber line. It will come up again in later reading, a little at a time, until you know it.
- If you hold Alt and rest on any word, marked or not, a quick translation appears and goes away when you move on.
02The word card
The word card
Opens when you click a marked word.
The card shows what yunit knows about the word. Keep adds it to your lexicon, and I know it tells yunit not to mark the word again.

- The word as it appears on the page.
- Plays the word in a voice for its language.
- Closes the card. Escape does the same.
- The translation in your language.
- Opens the definitions.
- The definitions from the dictionary, with the pronunciation.
- The sentence you found the word in. It is saved together with the word.
- Keep adds the word to your lexicon, and it will come up again in later reading.
- I know it tells yunit not to mark this word any more.
- A line on where the word stands. Sharpen asks for a better translation of a difficult phrase, which is part of Premium.

- Shows that the word is kept, when it was kept, and when it comes up next.
- Remove takes the word out of the lexicon again.
- Where the word stands now.
When a kept word comes up again to test you, the card opens without the translation, so you can try to remember it first.

- The word on the page, marked without its translation this time.
- Reveal shows the translation. The space bar does the same.
- Says why the card looks like this, the word is due for a recall.

- The translation, once revealed.
- Knew it means the word will come up again later.
- Forgot means it will come up again sooner.
03A phrase
A phrase
Select any words on a page while Translate selection is on in the popup.
A selected phrase is translated as a whole, right where you are. You can keep it as one entry, and the unfamiliar words inside it can be kept along with it.

- The words you selected.
- The translation of the whole phrase.
- Keep phrase adds it to the lexicon as one entry.
- If Keep unknown words from phrases is on in the popup, each new word inside the phrase is kept as well, and this line says how many.
- Plays the phrase.
- Closes the card. Clicking anywhere else does the same.
04The popup
The popup
The yunit button in the browser toolbar.
The popup opens on the page you are looking at and says what yunit is doing there. Your reading settings are underneath, and the ones you rarely change are folded under More.

- The main switch. Turning it off stops yunit on every page until you turn it back on.
- A sentence about the page you are on, which language yunit sees there and what it is doing.
- Pauses yunit on this site only, and resumes it later. Useful for a site you read in your own language.
- Sites… opens the list of sites where yunit is paused, or the list of the only sites where it runs, depending on how you keep the list.
- Your two languages, written as a sentence. Change either one and every page follows.
- How many words get marked. One dot marks a word here and there, and five marks as many as the page can take. Turn it down when a page feels crowded and up when you want more.
- Translate selection. When it is on, selecting text opens the phrase card. Turn it off if you often select text for other reasons.
- Pronounce on hover. When it is on, resting on a marked word plays it. Turn it off in a quiet room.

- More opens the settings you change rarely.
- Lyrics on YouTube. When it is on, music videos get the lyrics panel. Alt+Shift+L opens it by hand.
- Keep unknown words from phrases. When it is on, keeping a phrase also keeps each unfamiliar word inside it.
- Annotation size. Small stays out of the way, and Large is easier to read from further back.
- Annotations stay out of selection. When it is on, copying text from a page does not copy the translations with it.
