 "   * Provides command :XtermColorTable, as well as variants for different splits

 "   * Xterm numbers on the left, equivalent RGB values on the right

 "   * Press `#` to yank current color (shortcut for yiw)

 "   * Press `t` to toggle RGB text visibility

 "   * Press `f` to set RGB text to current color

 "   * Buffer behavior similar to Scratch.vim
