Make a directory on your home folder to keep all your softlinks. Make the directory name short. Maybe just one letter. I made mine s.
~$ mkdir s
Then make the link in there.
~$ ln -s /long/path/to/project/folder s/project
So now whenever you need to go there just key in:
And tab autocomplete helps a lot here. Maybe you just need to type 4 keys (including tab) if you haven't got much links yet. And in vim? :lcd s/project and BAM you're working you're way to oblivion. Nice eh...
