thank you for your replies but it was not really what I was looking for.

there was some nice info here and I used it to add tilde to the keybar

like I said I use aliases but I am looking for something else, I'll try to explain better this time.

there is a folder, I'll call him hank
I use hank a lot
I want a symbol, for instance @
and I want @ to act exactly like ~ but for hank instead of for home/user/

so that ls @/jack
becomes ls hank/jack

I hope this is more clear

Thanks in advance,
