General :: Minimize Typing When Frequently Changing Directories?

What are some good Linux commands to make switching between different directories on the command line easier?

I often have to switch between different directories with long names, e.g.

Typically, I use tab completion, so it's something like this:

But it's annoying because all these names are so similar, so tab completion doesn't really save much work.

What tricks do you use to minimize typing in such situations?

I do use pushd and popd sometimes, but here it won't help much because I don't visit the directories in a given order.

For a nice solution, see the accepted answer to my other, related question. Basically, just create an alternative cd command:

function cd2 { select a in $1*; do cd $a; break; done }

It will list all possible completions at once:

And you can pick one by typing its number.
