Micro also supports creating buffers from stdin:
These are the default keybindings, along with their actions.
-#### Editor bindings
-
* Ctrl-q: Quit
* Ctrl-e: Execute a command
* Ctrl-g: Toggle help text
* Ctrl-b: Run a shell command
-
-#### Buffer bindings
-
* Ctrl-s: Save
* Ctrl-o: Open file
* Ctrl-z: Undo
* Ctrl-c: Copy
* Ctrl-x: Cut
* Ctrl-k: Cut line
+* Ctrl-d: Duplicate line
* Ctrl-v: Paste
-* Ctrl-u: Half page up
-* Ctrl-d: Half page down
* PageUp: Page up
* PageDown: Page down
* Home: Go to beginning of line
You can hold shift with all of these movement actions to select while moving.
-The buffer bindings may be rebound using the `~/.config/micro/bindings.json` file. Each key is bound to an action.

### Options
Micro stores all of the user configuration in its configuration directory.
-Micro uses the `$XDG_CONFIG_HOME/micro` as the configuration directory. As per the XDG spec,
-if `$XDG_CONFIG_HOME` is not set, `~/.config/micro` is used as the config directory.
