It only just occurred to me, but there’s a reason its the E key which is starting to fail on my #Microsoft4000 #ErgonomicKeyboard - its the most used letter in the English language (and I'm not a vi/vim user so no HJKL effect - my cursor keys get pounded instead, and thankfully are holding up fine).
I guess switching to Dvorak would be one “solution" (becomes `.>`) , or Colemak (becomes F).
