Does zsh have bash's ESC+.?
Let's say you are about to finish a really long command and realize you should have done one other command first.
ESC + Q clears the current line, lets you enter a command, and then inserts the cleared line again on the next prompt. You have to try it to realize how cool it is.
ESC+. does not work for me with zsh.
zsh 4.3.11 (i386-apple-darwin12.0)
Maybe it's the version.
ESC+Q also doesn't clear the line.
At the same time, the OP links slide deck fails for me at the cd /u/lo/b part. It simply doesn't work.
I figured this was a default setting.
Esc-Q sounds easier, though.
