I’m selling a keyboard, the Y-SU61, that, in this specific version, has a keyboard UX issue fixed. Most of the other Y-SU61s don’t have this issue fixed… so these product names are not necessarily meaningful.
This keyboard is for beginners new to PCs. By removing the “insert” key from above the “delete” key, they avoided the problem of pressing the “insert” key and going into “insert mode”, and then typing, overwriting the text that was already there. Beginners don’t know what “insert mode” is, and and get confused when their typing wipes out the existing text. Typically, there’s no indication you’re in “insert mode”.
You can still go into insert mode by pressing “insert” on the keypad.
Having “insert” above “delete” implies that they will work similarly: pressing “insert” should insert a space to the right, just like how “delete” removes a character from the right. This function’s completely useless, but the positioning implies something like that. Alternatively, it could be labeled “backspace” and behave like the backspace key.
Look at the other keys. “Home” above “end”, and “page up” above “page down”. They act the same. The key above “delete” should do something related to “delete”.
Also, pretty obviously: “home” and “end” could be relabeled “top” and “bottom”.
We don’t notice these problems because we’re used to this screwed up keyboard.
However, if tablets really take over, we’ll be facing this problem again. Tablet users typically don’t have insert mode.
