+# dircycle
+
+Plugin for cycling through the directory stack
+
+This plugins enables directory navigation similar when using back and forward on browsers or common file explorers like Finder or Nautilus.
+
+This is a small zle trick that lets you cycle your directory stack left or right using Ctrl+Shift+Left/Right. This is useful when moving back and forth between directories in development environments, and can be thought of as kind of a nondestructive pushd/popd.
+
+## Enabling the plugin
+
+1. Open your `.zshrc` file and add `dircycle` in the plugins section:
+
+   ```zsh
+   plugins=(
+       # all your enabled plugins
+       dircycle
+   )
+   ```
+
+2. Reload the source file or restart your Terminal session:
+
+   ```console
+   $ source ~/.zshrc
+   $
+   ```
+
+## Usage Examples
+
+Say you opened these directories on the terminal:
+
+```console
+~$ cd Projects
+~/Projects$ cd Hacktoberfest
+~/Projects/Hacktoberfest$ cd oh-my-zsh
+~/Projects/Hacktoberfest/oh-my-zsh$ dirs -v
+0       ~/Projects/Hacktoberfest/oh-my-zsh
+1       ~/Projects/Hacktoberfest
+2       ~/Projects
+3       ~
+```
+
+By pressing <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd>, the current working directory or `$CWD` will be from `oh-my-zsh` to `Hacktoberfest`. Press it again and it will be at `Projects`.
+
+And by pressing <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd>, the `$CWD` will be from `Projects` to `Hacktoberfest`. Press it again and it will be at `oh-my-zsh`.
+
+Here's a example history table with the same accessed directories like above:
+
+| Current `$CWD`  | Key press                                             | New `$CWD`      |
+| --------------- | ----------------------------------------------------- | --------------- |
+| `oh-my-zsh`     | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd>  | `Hacktoberfest` |
+| `Hacktoberfest` | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd>  | `Projects`      |
+| `Projects`      | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd>  | `~`             |
+| `~`             | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> | `Projects`      |
+| `Projects`      | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> | `Hacktoberfest` |
+| `Hacktoberfest` | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> | `oh-my-zsh`     |
+| `oh-my-zsh`     | <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> | `~`             |
+
+Note the last traversal, when pressing <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd> on a last known `$CWD`, it will change back to the first known `$CWD`, which in the example is `~`.
+
+Here's an asciinema cast demonstrating the example above:

+
+## Functions
+
+| Function             | Description                                                                                               |
+| -------------------- | --------------------------------------------------------------------------------------------------------- |
+| `insert-cycledleft`  | Change `$CWD` to the previous known stack, binded on <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Left</kbd> |
+| `insert-cycledright` | Change `$CWD` to the next known stack, binded on <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Right</kbd>    |
+
+You can bind these functions to other key sequences, as long as you know the bindkey sequence:
+
+For example, these commands bind to Alt+Shift+Left/Right in xterm-256color:
+```
+bindkey '^[[1;4D' insert-cycledleft
+bindkey '^[[1;4C' insert-cycledright
+```
+
+You can get the bindkey sequence pressing <kbd>Ctrl</kbd> + <kbd>V</kbd>, then pressing the keyboard shortcut you want to use.
