NOTE: some terminals might override the ALT+Arrows key bindings (Windows Terminal, for example).
If these don't work check your terminal settings and change them to a different keyboard shortcut.
**For macOS: use the Option key (<kbd>⌥</kbd>) instead of <kbd>Alt</kbd>**.

## Usage
This plugin allows you to navigate the history of previous current-working-directories using ALT-LEFT and ALT-RIGHT. ALT-LEFT moves back to directories that the user has changed to in the past, and ALT-RIGHT undoes ALT-LEFT. MAC users may alternately use OPT-LEFT and OPT-RIGHT.
This plugin allows you to navigate the history of previous working directories using <kbd>Alt</kbd> + <kbd>Left</kbd>
and <kbd>Alt</kbd> + <kbd>Right</kbd>. <kbd>Alt</kbd> + <kbd>Left</kbd> moves to past directories, and
<kbd>Alt</kbd> + <kbd>Right</kbd> goes back to recent directories.
Also, navigate directory **hierarchy** using ALT-UP and ALT-DOWN. (mac keybindings not yet implemented). ALT-UP moves to higher hierarchy (shortcut for 'cd ..'). ALT-DOWN moves into the first directory found in alphabetical order (useful to navigate long empty directories e.g. java packages)
**NOTE: the maximum directory history size is 30.**
You can also navigate **directory hierarchies** using <kbd>Alt</kbd> + <kbd>Up</kbd> and <kbd>Alt</kbd> + <kbd>Down</kbd>.
<kbd>Alt</kbd> + <kbd>Up</kbd> moves to the parent directory, while <kbd>Alt</kbd> + <kbd>Down</kbd> moves into the first
child directory found in alphabetical order (useful to navigate long empty directories, e.g. Java packages).
For example, if the shell was started, and the following commands were entered:
@ -35,8 +43,20 @@ cd share
cd doc
```
Then entering ALT-LEFT at the prompt would change directory from /usr/share/doc to /usr/share, then if pressed again to /usr/, then ~. If ALT-RIGHT were pressed the directory would be changed to /usr/ again.
the directory stack (`dirs -v`) would look like this:
After that, ALT-DOWN will probably go to /usr/bin (depends on your /usr structure), ALT-UP will return to /usr, then ALT-UP will get you to /
```console
$ dirs -v
0 /usr/share/doc
1 /usr/share
2 /usr
3 ~
```
**Currently the max history size is 30**. The navigation should work for xterm, PuTTY xterm mode, GNU screen, and on MAC with alternate keys as mentioned above.
then entering <kbd>Alt</kbd> + <kbd>Left</kbd> at the prompt would change directory from `/usr/share/doc` to `/usr/share`,
then if pressed again to `/usr`, then `~`. If <kbd>Alt</kbd> + <kbd>Right</kbd> were pressed the directory would be changed
to `/usr` again.
After that, <kbd>Alt</kbd> + <kbd>Down</kbd> will probably go to `/usr/bin` if `bin` is the first directory in alphabetical
order (depends on your `/usr` folder structure). <kbd>Alt</kbd> + <kbd>Up</kbd> will return to `/usr`, and once more will get
you to the root folder (`/`).
