What are the buttons on logitech ce 0678 keyboard

It sounds like you are trying to use the same formatting settings on your new Logitech keyboard that you had on your old Logitech keyboard, but the formatting button is not present on the new keyboard.
To add the formatting button to your new Logitech keyboard, you will need to do the following:

1. Open the Logitech Options software. This software allows you to customize the settings and functionality of your Logitech keyboard.
2. Select the "Buttons" tab. This will allow you to customize the buttons on your keyboard.
3. Find the formatting button that you want to add. Depending on the model of your keyboard, you may have the option to add a variety of formatting buttons, such as bold, italic, and underline.
4. Assign a function to the button. To add the formatting button to your keyboard, you will need to assign a function to it. Click on the button and then select the formatting function that you want to use.
5. Save the changes. Once you have added the formatting button and assigned a function to it, click the "Apply" button to save the changes.

I hope this helps! Let me know if you have any other questions.

You can find something at open source.

at the keyboard must have its own receiver which is connected to usb
most likely it does not support Bluetooth

Perhaps this will help Support Cobra Electronics Corporation

I forgot password and can't access in my HTC tytn II, now how can I solve this problem because I need all information????

Install the drivers for the keyboard and mouse (either from the included disc or Logitech's website) and then plug them in.

may not be compatible,
or you ay need new batteries for the keyboard

did this come with software
and you might need to do a uninstall reinstall
if it worked on same pc before it should work now.
if you have a reset button on transmitter try resetting it.
