Yup! You can also add specific buttons that might not be "mapped" for a particular device code.

For example, I have a Humax digital set top box, come PVR. The code for it was readily available on the remote, but it was missing the recorded programmes shortcut key, that I regularly use. Took less than 5 minutes to add the button, label it and learn the code - though note that lower case lettering is only available when using the included software.

Oh, and another word of warning. When installing the battery, keep fingers away from any buttons and the touchscreen. I didn't and found the default language had changed from English to Danish. Took me an hour or more to work my way back to the settings page to change it back.
