I like to create a custom keymap for my iOS devices by duplicating the keyboard.xml file and adding the following customization to the <home> section. This affects how swipe left and swipe right act at the homescreen. Allows me to swipe left and right to move the highlighted item.
Code:
<Home>
<keyboard>
<!-- SwipeLeft --> <backspace>Left</backspace>
<!-- SwipeRight --> <tab>Right</tab>
</keyboard>
</Home>
Here's a zip file containing the keyboard.xml file with the modification mentioned above already added.

Simply unzip it and upload it to your iPad.
It's important to log in as:
user: mobile
pass: alpine
Logging in as the mobile user instead of root ensure the proper permission is set whenever you add anything to the userdata directories.
Here is the path to the userdata directory. You need to upload your custom keymap file to the keymaps folder located at this path:
/var/mobile/Library/Preferences/XBMC/userdata/keymaps/
Once you upload the keyboard.xml file there, bring up the multitask switcher to ensure that the XBMC application is not running in the background. Then launch XBMC and try swiping left and right. Should make navigating the homescreen much easier.
You can read this recent thread for even more nuggets of info on what you can do to make the whole XBMC experience on the iPad and iPhone better.
