Hello there, Mr. I-Only-Have-a-Left-Hand.

I use the right control keys, I use Ctrl+Ins/Del, I use "Context menu" key, when it's available. And hey, I have almost a 30 years of muscle memory for them, so when some another idiot replaces the right Ctrl with F23 (which even can't be remapped by default AND pops up the stupidest menu for selecting what F23 should do) I really what to punch him in the face.

NB: as someone up in the thread mentions, right Ctrl is extremely useful for navigating in the text.
