Spelling mistakes, mistakes that exist in another locale and incorrect
case are now all different colors, and those along with a few other
colours have been tweaked to better matches the theme, and the non-colour
term theme should more closely match too. The F1-F3+F12 toggles
now work in all three editor modes, and F4 has been added to toggle
spellcheck, which also works in all three modes (depending on the
filetype, sometimes it will start on and others off). You can now place
your cursor on an misspelled word in normal mode and hit \\ (backslash
twice) to create a drop down menu with suggestions.
