I made some adjustments to see a large-sized video with its script without clicking the page flip button.

You can adjust video size and layout by changing “–height_big” variable’s value only, others are automatically adjusted.
If it’s useful, plz hit the like button below.
- You need to change the background color to dark manually or change the color settings.
- If the video size is small, you need to expand the video window by pressing
Q key.

Any way to change the punctuation color as well? The white really stands out if the font color is set to gray.
Change
.reader-container p span.sentence-item {
color: var(--font_color) !important;
}
to
.reader-container p .sentence-item, .reader-container p .sentence {
color: var(--font_color) !important;
}
Now it works.

Yes, that works, thank you.

New Feature:
- Now the sentence playing is located at the center of the screen. You don’t need to scrol acording to the playing video.
If you don’t want the sentence is fixed on the exact center use nearest instead of center in this part of the code playingSentence.scrollIntoView({behavior: 'smooth', block: 'center'});
It always locates the sentence inside a screen but not center.

New hotkeys
- Move the cursor to the reference input (`): it directly moves the keyboard cursor to the text field in the widget.
- Open Dictionary (d or f): it works when multiple words are selected
- Open Translator (t): it works when multiple words are selected
- Copy selected text (c): copy selected text in a clipboard (I use it when using LLM)
Of course, you can change the hotkeys in your favor.
The Open Dictionary key clicks the first dictionary and the Open Translator selects the last. So you need to set them properly
You can change the order of the dicts here.

I’ve yet to figure out how to enable this script via tampermonkey. Tampermonkey us enabled, I pasted in the script provided and saved it, that’s now in the extension an turned on, I’ve reloaded, nothing works. I’ve enabled developer mode for TM too. I watched a couple videos, nothing is showing the missing step unfortunatly.

I’m not sure what the problem is with it.
This is the process i had and works. Uninstall the extension and follow the procedure.
- install Tampermonkey from chrome store
- open Extension from the upper navbar and click ‘Create a new script’ button.
- Copy and paste the script I provide.
- refresh LingQ reader page.
It could be the issue with the URL format. Let me know the URL of your reader page. Browser also.
Ok I followed those instructions. This time something change a little but nowhere close to what it shoud look like, and I tried it on a clean account with no other extensions which could possibly interfere. I tried it within firefox too and the same weird / incomplete effect happens.
Here is the url I’m on for reader mode:
What it looks like for me:
What I pasted in (beginning and end):
Enabled:
This is the layout I intended. It seems to work on your PC.
Hit the ‘Q’ key after loading the video to expand the video and fill its area.
If the video size is too large, adjust –height_big variable
If your monitor’s resolution is too low, you might need to change the fontsize and video size to reserve enough space for text.
This is 1920x1080 setup

Q Key! Ok that resolved it and then I feel like I dope, I was expecting darkmode to be turned on via the script and I realized I needed to enable that seperatly in LingQ settings. Anyway, all good now, thanks for the help!
Yup. Have a good night or day!

How can I change this situation??
Click the Aa button in the upper right corner and select the black background color. If you prefer light mode, change color values in the source code.

It hides the annoying “more videos” popup and the YT logo from the mini video player.
You can read subtitles when a video is paused.
Use it together with my LingQ Add-on script.

In the default lingQ interface, the state 4 of the word will hide the yellow prompt, but the yellow prompt will still be displayed under the script, how can I change the target, and the yellow prompt will be hidden when the state 4 is hidden?
I intentionally maintained the border of the known words. If you don’t like it, change the code.
--lingq_border_learned: hsl(43 99% 64% / 0.5);
to
--lingq_border_learned: hsl(43 99% 64% / 0);
Additional Tip
You can open DevTools with F12 key. There, you can change the variables interatively. Use it when you test UI elements.
(The change made here is not saved, so make sure that you change the corresponding script’s values.)
Change Log
v1.6: Now, LingQ uses “youtube.com” player, not “youtube-nocookie.com”. Some code is updated for that change.
Also, now the videos you watch in LingQ show up in YouTube watch history (previously not). In other words, YT algorithm will consider the video played in LingQ.
LingQ automatically play the video, and auto-played video doesn’t counted as a view. So, not appear in YT history page.
