Docs page enhancements

[suntong]

Interactive, editable examples of all major widgets are available on the main docs page (which is also a Cogent Core app running via wasm).

Here is what issues I found about our docs site.

• Copy & paste not possible, at least with my Linux Chrome. This makes it hard for people to follow the instructions as-is, and tiny typos will make getting started to have more hurdles.
• Search is not possible, when I type something in my search box and hit enter, I'm getting this:

Meanwhile, where is the source text for our main docs page please?

Thank you for filing this. The source for the docs is in the docs directory, mainly the docs/content directory. It is built using pages, which you can read about here. I am working on improving the search setup. I am also working on improving the selection support for copy and paste (see #1051).

I noticed that double clicking a word in the docs selects the whole paragraph instead of the word, also right click doesn't display the usual menu, seems like something is overriding default os behaviours.

[kkoreilly]

Yes, we are overriding default os behaviors, which is necessary for the event system to work correctly. We just need to improve text selection (#1051).

I just noticed that middle clicking which should open the underlying link in another tab is not working either.

[kkoreilly]

Yes, I will also work on fixing that.
