 - If the line you want is far back in the history, type any part of the line and then press Up one or more times.  This will filter the recalled lines to ones that include this text, and you will get to the line you want much faster.  This replaces "!vi", "!?bar.c" and the like.

 fish suggests commands as you type, based on `command history <#history-search>`_, completions, and valid file paths. As you type commands, you will see a suggestion offered after the cursor, in a muted gray color (which can be changed with the ``fish_color_autosuggestion`` variable).

 Autosuggestions are a powerful way to quickly summon frequently entered commands, by typing the first few characters. They are also an efficient technique for navigating through directory hierarchies.

 After a command has been entered, it is inserted at the end of a history list. Any duplicate history items are automatically removed.
