Say you want to go to "/usr/local/share/fonts" but that's too much to type out, you can instead type "cd /u/l/s/f" and hit tab. If every path element is unambiguous it will just expand it to "/usr/local/share/fonts". In this case though, "/u/l/" can expand to "/usr/local" or "/usr/lib" so when you hit tab it moves the cursor to just after the "l" to indicate it needs you to distinguish between "/usr/local/" and "/usr/lib". If you just type "o" and hit tab again, it will know that there's only one match for "/usr/lo" and expand that to "/usr/local/" Then there's only one match for "s" which is "share", and only one match for "f" which is "fonts".

That avoids the danger of executing a command with an asterisk wildcard.

works in fish shell as well.
