Window commands that I use all the time:

  • <C-w> o - closes all other windows besides the current one.
  • <C-w> ^ - go to the "alternate file". Very useful for swapping between 2 most recent files.
  • <C-w> T - if you have a window open in a split and you want to move it to a new tab, focus the window and execute this mapping.
  • Remap <C-w> [h,j,k,l] to just <C-[h,j,k,l> for much easier buffer navigation.
