make #+BEGIN_EXTRA an easy to type <admonition

[thiswillbeyourgithub]

Describe the solution you'd like
Typing < makes the admonition enter popup appear, I'd like to have a choice for "extra" that would type #+BEGIN_EXTRA\n\n#+END_EXTRA

Describe how it will help your workflow
I currently use this extra field for sources and it would be handier to type

Describe alternatives you've considered
None satisfactory

Not using this currently but I've seen e.g. Dario on YT use something like autohotkey to define stuff like this for himself. E.g. he has an article-input template that is activated by some sequence of keys.
Maybe that would be an acceptable workaround?

You know what you're right. I'm already using autokey (iirc the name) on linux. If the author has time I still think it's a feature that would help others.

I guess this is the limitation of the logseq itself, since it uses markdown for writing and HTML for visualizing.

in comparison,
Craft app has a lot of intuitive shortcuts and buttons to implement many functions.
(although, I still prefer much more on logseq for the speed and flexibility)

I guess just using macro keys is the best alternative since it could be done in an easy way.

or just create a templet in logseq then use slash command for easy workdone.
(I saw many people doing this)
