# Shift Tab Addon
The addon has four keymaps:
- Go to next tab using `Alt + l`
- Go to previous tab using `Alt + h`
- Move current tab to the right with `Alt + L`
- Move current tab to the left with `Alt + H`

## Important Note
For the plugin to be able to use `Alt + h` and `Alt + H`, you must disable the `menuAccessKey`. This is the key that opens the menu (for example, `Alt + h` to open Help in Firefox).
## How to Disable the Key
Follow these steps to disable the key:
1. Open your browser and enter `about:config` in the URL bar.
2. Click on **Accept the Risk and Continue**.
3. In the search bar, enter `ui.key.menuAccessKey`.
4. Set `ui.key.menuAccessKey` to `0`.
