Right now if you create a code-block, it creates a block level element that disallows selecting the contents unless you double click on the element and copy the code. I know there is a plugin that adds a "Copy Text" icon, but it would be great if there was a configuration option that would just allow us to select the text inside a code-block just like any other text.
BUT... The interest of the block code format
is maybe precisely to protect the text from being erased or modified by mistake by a simple selection. Otherwise there's not much utility to the "code" formatting... So the opportunity or not to select immediately the text of a block code should be an option to check and not something permanent...
By the way the inline code allows the direct selection...
