Starting a few days/updates ago, the normal (left) Ctrl Shift C / Ctrl Shift V stopped working. And Ctrl+Ins and Shift+Ins does Not work for me. Reading thru the related topics, just tried (right) Ctrl Shift C / Ctrl Shift V and it works as the original (left) Ctrl Shift C / Ctrl Shift V used to do. So for whatever the reason, left Ctrl stopped working, but right Ctrl does. Thankfully!
