I have a general question about the linux terminal:

Is there a way to make your own ~?

~ is nice for when you want to go to home, but if there is another folder that you use a lot, can you choose another symbol that has the same effect for folder as ~ has for home?

I now use aliases like this:
cdf
lsf

to cd and ls to f, where f is the folder I use a lot, but having a symbol like ~ would make it easier since I often want to cd/ls to other folders within f.

Does anybody have an idea?

Thanks in advance,
