This button could be applied for more special or specific applications such as a uncommon food mod.
The main thing that prompts for the keyboard is the ? attached to the item name.
Adding Keyboard Item
- Use 'Add Like' from any merchandise item, give it a new name and make sure to add a question mark with no space at the beginning. (preferably ?keyboard for clarity and ease of use)
- Go through the tabs on the merchandise item and clear out any unnecesarry additions (prices, links, tax info)
- Make sure the 'prompt for price' checkbox in the general tab is unchecked.
- You can keep the other checkboxes the same depending on the location and use case.

It is helpful to keep the keyboard button in a different location (disp button) and set as a different color (color dropdown menu) to make it more distinguishable.
- If you decide to not use add like, just make sure the new item you are creating has the unattached question mark in the beginning
(ex: ?keyboard, ?special mod)
