I'm watching the great Emacs Rocks! Episode 13: multiple-cursors vide at youbube: https://www.youtube.com/watch?v=jNa3axo40qM
There are several places I'm not clear how the author did it. At 0:32: https://youtu.be/jNa3axo40qM?t=32, how the author quickly deletes strings from the underscore character to the end of the words?
At 0:39:https://youtu.be/jNa3axo40qM?t=39, how does the author quickly select the strings like
class="fruit"? I guess it's a shortcuts from the html-mode but I can't find anything useful.
