Avail yourself of one of the templates here:

Switch page template

Keyboard page template

Edit these pages and copy and paste the entire contents to your new page. You can create a new page from the root of each category or from the sidebar in each category. Alternatively, you can type the page in the search box and you'll be offered the chance to create it. Pages always have a namespace, so for keyboards you'd want to do something like 'keyboard:my_cool_keyboard' or 'switch:my_cool_switch' in the search box.
