I never started with Vimium (was using an even less known one), also in part because I find smooth scrolling disorienting. Also on Tridactyl now, once someone on here showed me the hintfiltermode, hintchars, and hintnames settings to get the old Vimperator behavior (which I also find so much better than any current defaults):

  set hintfiltermode vimperator-reflow
  set hintchars 1234567890
  set hintnames numeric
