In my bash shells, I hit ESC and 'd'.

Anybody knows if there is a counterpart for CTR+w , that deletes immediate words after cursor
I'm trying to make a cheat-sheet for my Math class. I wonder is there a way to scale the entire document so that I can fit more formulas and theorems into it. It doesn't need to be super tiny though. I tried tiny font, but it still waste too much space. Have anyone done it before could share me some experiences? Thanks in advance.
