This is a Wikipedia page dedicated to helping out.
If you are looking for keyboard short-cuts, press Ctrl, Alt, and Slash. This will pop up a new window that will start out showing you popular shortcuts. If you are looking for a specific shortcut, go up to the search bar in this window and search for whatever you want. To use the talk feature on Wikipedia, look right above the title of the article you are reading. You should see 2 small tabs. You have User page selected, but if you tap on the tab next to it, ¨Talk¨ you can send me a message by going to the top right above the article, and hitting edit. Then you edit the page below any other comments and scroll down, hitting publish changes.
If you have any questions about technological tidbits, go to the talk feature and send me a message. I will try to reply daily to as many people as possible.
