Some nearby neighbors think it’s a distinct variety of lemon, others think it must be some lemon/orange hybrid. I wonder if any Dopers know of this kind of lemon? The lemons are nearly spherical, almost-but-not-quite like oranges. They are definitely lemon-yellow. They taste like lemons, but sweet enough to eat straight, like an orange. They are somewhat lemonade-sweet (but not too sweet) and somewhat le… ---

There are split keyboards. You can do a google image search for split keyboards to see pictures of many models. I don’t know about how the trackball placement goes. You could probably jury-rig some way to attach to your chair arms. ---

> [@TRC4941](#): > > Also, all cans (vegetables, soups, tuna, etc) should come with a ring/pop-top. I notice there are a lot more of these cans lately. But they all should be like this by now.   Some of those are more difficult to open than others. For those of us with ancient arthritic fingers, it can be all the more difficult and unpleasant. Such cans _might_ be openable with a regular can opener, depending on the can and the can opener. A while back, I asked if there is a tool for opening these pop-top cans, and we had a thread about that: > [@Opening pop-top cans](https://boards.straightdope.com/t/opening-pop-top-cans/955521): > > A lot of canned foods now come in those pop-top cans – the kind where you pull the entire top off. I have a hard time with some of those, due in part of increasing arthritis or maybe just general old-age decrepitude. Can anybody recommend an alternative way of opening these? Is there some trick using any tools I might have around the kitchen? Are there any kitchen tools out there specifically designed to open lids like this? (Some such cans can be opened with a can opener, but not most that… ---

You could probably jury-rig some way to attach to your chair arms. True, however, this concept first occurred to me back in the late '90s and, at that time, I assumed that someone would develop (properly as opposed to velomont duct-taping half keyboards to his chair arms 😀).
