# Variable aliases and more
There are no aliases I have to make now.
But there are something to see:
## *NIX shell syntax
If you see something like `-{,{mouse,finder}}`, it's the same as:
* `-`
* `-mouse`
* `-finder`
No space between `mouse` and `finder` is indentional. If there's one then we will have:
* `{mouse, finder}` => `mouse` and ` finder`;
* `{mouse ,finder}` => `mouse ` and `finder`
