   Wave allows you to create your own custom commands by modifying the *command* and *commandStr* fields.
   - In the *command* field, use the `custom:` prefix, along with your command name, to add a custom command name.
-  - In the *commandStr field*, add a custom command using a [slash command](/reference/slashcommands), or a shell command.
+  - In the *commandStr field*, add a custom command using a [slash command](/reference/slashcommands), shell command, or a combination of both.

+**Note:** If you want to use a keybinding that is already occupied by a system command, you will first need to assign a new keybinding to the system command. Once you have freed up the desired keybinding, you can then assign it to your custom command in the `keybindings.json` file.

+  <Accordion title="Example">
+To reassign the `Cmd+b` keybinding to your custom command, you would need to:
+
+1. Add the default "Open Bookmarks View" command in the `keybindings.json` file and asign it a different keybinding, such as `Cmd+Shift+b`:
+```json
+{
+  "command": "app:openBookmarksView",
+  "keys": ["Cmd+Shift+b"],
+  "commandStr": ["/bookmarks:show"]
+}
+```
+2. Add a new entry in the `keybindings.json` file for your custom command, assigning it the `Cmd+b` keybinding that was previously occupied by the "Open Bookmarks View" command:
+
+```json
+{
+  "command": "custom:openFolder",
+  "keys": ["Cmd+b"],
+  "commandStr": ["cd ~/Projects/MyFolder"]
+}
+```
+Now, when you press `Cmd+b`, it will execute your custom command. Also, the "Open Bookmarks View" command will still be available, but it will be triggered by the new keybinding `Cmd+Shift+b`.
