 - Each keyboard shortcut for start/stop recording and playback is assigned to the same ones that the original editor is using, as much as possible.
-- Since Atom seems to not have macro recording functionality, I set them to the default of this extension.
-- Some shortcuts in the above table are overriding the default shortcuts of VS Code such as Command Palette (`Ctrl/Cmd+Shift+P`) unintentionally.
 - You can find the definitions of them at the bottom of each keymap wrapper file (find the `startRecording` command etc.). You can customize them as you like.
-- The `S-9` and `S-0` in the row of Awesome Emacs Keymap are meant to be `(` and `)` on the US keyboard. We had to write in such a way because VS Code seems to not allow using `(` or `)` in keybindings.

+- Notes on **Awesome Emacs Keymap**:
+    - You can also use the emacs-style prefix-arguments with the playback command! For example `C-u 7 C-x e` will playback the sequence 7 times. Please be sure that you are using the Awesome Emacs Keymap v0.37.0 or later. Thanks to [@whitphx (Tsuchiya)](https://github.com/whitphx) for the collaborative work!
+    - The `S-9` (`shift+9`) and `S-0` (`shift+0`) in the table are meant to be `(` and `)` respectively on the US keyboard. We had to write them in such a way because VS Code seems to not allow using `(` or `)` in keybindings. If your keyboard has a different layout, please adjust the keybindings by yourself.
