+# toggle-view.yazi
+
+Toggle the different views: parent, current and preview.
+
+## Requirements
+
+- [Yazi](https://github.com/sxyazi/yazi/) v0.4 or later.
+
+## Installation
+
+```sh
+ya pack -a dawsers/toggle-view
+```
+
+## Usage
+
+Add this to your `~/.config/yazi/keymap.toml`:
+
+``` toml
+[manager]
+prepend_keymap = [
+    { on = "<C-1>", run = "plugin toggle-view --args=parent", desc = "Toggle parent" },
+    { on = "<C-2>", run = "plugin toggle-view --args=current", desc = "Toggle current" },
+    { on = "<C-3>", run = "plugin toggle-view --args=preview", desc = "Toggle preview" },
+]
+```
+
+Now each key will toggle on/off one of the three panels: `Ctrl+1` for
+*parent*, `Ctrl+2` for *current* and `Ctrl+3` for *preview*.
+
+You can set your own key bindings.
