+User Menu is a power feature of `Cloud Commander` that was added in [v12.2.0](https://github.com/coderaiser/cloudcmd/releases/tag/v12.2.0).
+
+If you create file `.cloudcmd.menu.js` in the `HOME` or any top-level directory, it will be used when you press
+`F2`. If you enabled it before with help of `--user-menu` command line flag.
+
+Here you can find ready to use scripts for your `user menu`.
+
+## Rename file
+
+The simplest way to show rename file dialog.
+
+```js
+module.exports = {
+    'F2 - Rename file': async ({DOM}) => {
+        await DOM.renameCurrent();
+    },
+};
+```
+
+## Convert flac to mp3
+
+```js
+
+const isMp3 = (a) => /\.mp3$/.test(a);
+
+module.exports = {
+    'F - Convert flac to mp3': async ({DOM, CloudCmd}) => {
+        const convert = 'for f in *.flac; do ffmpeg -vsync 2 -i "$f" -b:a 320k "${f%flac}mp3"; done';
+        const command = `bash -c '${convert}'`;
+        
+        const exitCode = await CloudCmd.TerminalRun.show({
+            command,
+        });
+        
+        if (exitCode)
+            return;
+        
+        await CloudCmd.refresh();
+        
+        const {IO, CurrentInfo} = DOM;
+        
+        // get mp3 file names
+        const {dirPath, files} = CurrentInfo;
+        const names = DOM.getFilenames(files);
+        const mp3Dir = `${dirPath}mp3`;
+        const mp3Names = names.filter(isMp3);
+        
+        // create mp3 directory
+        await IO.write(`${mp3Dir}?dir`);
+        
+        // move *.mp3 files to a mp3 directory
+        await IO.mv({
+            from: dirPath,
+            to: mp3Dir,
+            names: mp3Names,
+        });
+        
+        await CloudCmd.refresh();
+    },
+}
+```
+
+## Create User Menu File
+
+```js
+ module.exports = {
+    'C - Create User Menu File': async ({DOM, CloudCmd}) => {
+        const {CurrentInfo} = DOM;
+        
+        const {dirPath} = CurrentInfo;
+        const path = `${dirPath}.cloudcmd.menu.js`;
+        const {prefix} = CloudCmd;
+        
+        const data = await readDefaultMenu({prefix});
+        await createDefaultMenu({
+            path,
+            data,
+            DOM,
+            CloudCmd,
+        });
+    },
+};
+
+async function createDefaultMenu({path, data, DOM, CloudCmd}) {
+    const {IO} = DOM;
+    
+    await IO.write(path, data);
+    await CloudCmd.refresh();
+    
+    DOM.setCurrentByName('.cloudcmd.menu.js');
+    
+    await CloudCmd.EditFile.show();
+}
+
+async function readDefaultMenu({prefix}) {
+    const res = await fetch(`${prefix}/api/v1/user-menu/default`);
+    const data = await res.text();
+    
+    return data;
+}
