+We need to define `key` and `character` in a `CharacterShortcutEvent` object to customize hotkeys. We recommend using the description of your event as a key. For example, if the underscore `_` is defined to make text italic, the key can be 'Underscore to italic'.
 
-> The command, made up of a single keyword such as `underscore` or a combination of keywords using the `+` sign in between to concatenate, is a condition that triggers a user-defined function. To see which keywords are available to define a command, please refer to [key_mapping.dart](../lib/src/service/shortcut_event/key_mapping.dart).
-> If more than one commands trigger the same handler, then we use ',' to split them. For example, using CTRL and A or CMD and A to 'select all', we describe it as `cmd+a,ctrl+a`(case-insensitive).

-Then, we need to determine if the currently selected node is a `TextNode` and if the selection is collapsed.
-
-If so, we will continue.
+Now our 'underscore handler' function is done and the only task left is to inject it into the AppFlowyEditor.
 
 ```dart
-// ...
-ShortcutEventHandler _underscoreToItalicHandler = (editorState, event) {
-  // Obtain the selection and selected nodes of the current document through the 'selectionService'
-  // to determine whether the selection is collapsed and whether the selected node is a text node.

-  if (selection == null || !selection.isSingle || textNodes.length != 1) {
