Hi Yulin-Rog, you need to install the new version of the code. Here is the link with what you need plus three demo videos:
https://c3founder.github.io/Roam-Enhancement/
hi, There is no alt key for mac, what shortcut can I use? a lot of thanks.
Hi, you can see all of the possible key combinations here:
https://craig.is/killing/mice
I don't have Mac but I assume you can replace all 'alt' with 'option' and things should work.
thanks
I replaced all 'alt' with 'option', and when I type 'option+a+t' in a child block of the YT video, it just shows 'å†', nothing else happened, then I replaced all 'option' with 'command', nothing changed neither.🤣
P.S. I only install the code above,
thanks

I have the same problem...😂
A couple of points to test/consider:
- You need roam42 installed.
- I was told by other mac users (@abhay) that the weird 'å†' can be fixed as follow: "you can disable the special characters by switching your input keyboard to Unicode HEX"
- Make sure that they are no other conflicting extension that uses alt+a. For example, I was told that the roam highlighter uses that.
thanks

@growingtreesss @CherryC99 Just use ctrl
@c3founder thanks for your patience and kind advices
@alanzchen thanks for your kind advice also
I tried the methods you mentioned above:
- Yes. even tried roam42 test version once(deleted later), roam42 preserved.
- successfully switching to Unicode HEX, 'option' or 'ctrl' didn't work
...then I used a Win to check , press "alt+a+n" , no response
my workflow is:
- install roam42
- install codes in https://c3founder.github.io/Roam-Enhancement/
- embed youtube video in roam
- use shortcuts in a child block of the YT video
Are there any steps I'm missing?

same error ! windows doesn't work! If there is a button, testing is easier. The shortcut often conflict!!

I want to make this question/answer more structured. Can you please initiate an issue here:
https://github.com/c3founder/Roam-Enhancement/issues
Also, sorry that I'm checking the basics but this can happen, make sure that the code block is indented under {{[[roam/js]]}}.
the issue is updated here c3founder/Roam-Enhancement#1
Why is it like that?
I'm using a mac. I've changed the shortcuts to ctrl+a n and ctrl+a t but for some reason it's not picking up the change. The new shortcut is does nothing but the original alt+ still works (even though I'm on a mac). Any ideas?
Hi having trouble installing. When I copy from https://c3founder.github.io/Roam-Enhancement/ nothing changes to my embedded youtube videos. I am indenting and placing it correctly, I have installed other roam/js code blocks without issue.
I can get the rounded corners on my youtube videos but only if I place this https://gist.github.com/c3founder/0d47fe3f15f677a0a6f0e96b4868e46a#file-responsive-timestamped-youtube-js
in to the javascript code block. But I don't have the timestamp button. I also don't have the ability to resize the youtube window. I really like the idea of working with youtube videos in Roam research. Any help would be appreciated!
Also the page, if entered in to a browser window, https://c3founder.github.io/Roam-Enhancement/enhancedX.css
States that the above file can not be found. It is giving me a 404 error.

Why is it like that?
I have not written the corresponding smart block and have no idea why it is not working with the YT extension. If you are using it for the button that inserts timestamps you can add it as a feature request in issues here.

Hey,
X here is a template!
https://c3founder.github.io/Roam-Enhancement/enhanced**X**.css
e.g., use this for YT:
@import url('https://c3founder.github.io/Roam-Enhancement/enhancedYouTube.css');
Hi there! I think i installed roam/js and code for Timestamp properly, but its not functioning after I implement the code and relaunching the browser multiple times😭 I mean it look the same as the original embed, cant resize, cant grab timestamp
any help on that plz?
