 ### Find a directory then `cd` to it:

 You can this way navigate to a directory with the minimum amount of keystrokes, even if you don't exactly remember where it is.
 
 broot is fast and never blocks, even when you make it search a big slow disk (any keystroke interrupts the current search to start the following one).

+Complex regular expression are possible, but you'll probably most often use a regex to do an "exact" search, or search an expression at the start or end of the filename.

+For example, assuming you look for your one file whose name contains `"abc"` in a big directory, you may not see it immediately because of many fuzzy matches. In that case, just add a slash at the end to change you fuzzy search into an exact expression: `abc/`.
+
+And if you look for a filename *ending* in `"abc"` then you may anchor the regex: `abc$/`.

 Just find the file you want to edit with a few keystrokes, type `:e`, then `<enter>` (you should define your prefered editor, see [documentation](documentation.md#verbs)).
