Git: Stash unstaged changes

This will stash all modifications that you did not git add:

Copygit stash -k

Note that newly created (and non-added) files will remain in your working directory unless you also use the -u switch.

Copygit stash -k -u

Also, your working directory must be clean (i.e. all changes need to be added) when you git stash pop later on.
