> All of that can be done much more efficiently without the mouse:
Surely we don't need to get into this sort of thing here.
If you don't know how to do it without the mouse, then it's more efficient to do it with the mouse. If you don't remember how to do it without the mouse, then it's more efficient to do it with the mouse. If you just like using the mouse better, then ….
Anyway, and perhaps more importantly, it doesn't hurt any of us if anyone else values ease of use (even if it's illusory or temporary!) over efficiency.
Yes, there is. "Best" is a harder subject to tackle, but there's always "better".
di{ is obviously both quicker and more precise than reaching to the mouse, pointing at the beginning of the code block, extending the selection until the end of the code block and hitting backspace.
One may think these keybindings are awkward or hard to remember (I did, at first, they are not) but they are both faster, more efficient and more deterministic by nature. But I may be a control freak. :-)
It's a subjective experience. I, too, prefer to use the keyboard as much as possible but I've also encountered doofuses that mock that position because the mouse is "so convenient" and "there's no way it's faster to use the keyboard entirely". So I guess their better is different from my better.
