   "A bitmapped button is a push button that uses one or more texture images for rendering its individual states.\n\n"
   
   "To find the individual textures associated with the button, a naming scheme is used.  For each state "
   "a suffix is appended to the texture file name given in the GuiBitmapButtonCtrl::bitmap field:\n"
   
   "- \"_n\": Normal state.  This one will be active when no other state applies.\n"
   "- \"_h\": Highlighted state.  This applies when the mouse is hovering over the button.\n"
   "- \"_d\": Depressed state.  This applies when the left mouse button has been clicked on the button but not yet released.\n"
   "- \"_i\": Inactive state.  This applies when the button control has been deactivated (GuiControl::setActive())\n\n"
   
   "If a bitmap for a particular state cannot be found, the default bitmap will be used.  To disable all state-based "
   "bitmap functionality, set useStates to false which will make the control solely render from the bitmap specified "
   "in the bitmap field.\n\n"

   "allows to associate different images and different actions with a button depending on which modifiers are pressed "
   "on the keyboard by the user.\n\n"
   
   "When enabled, this functionality alters the texture lookup above by prepending the following strings to the "
   "suffixes listed above:\n"
   
   "- \"\": Default.  No modifier is pressed.\n"
   "- \"_ctrl\": Image to use when CTRL/CMD is down.\n"
   "- \"_alt\": Image to use when ALT is down.\n"
   "- \"_shift\": Image to use when SHIFT is down\n\n"
   
   "When this functionality is enabled, a new set of callbacks is used:\n"
   
   "- onDefaultClick: Button was clicked without a modifier being presssed.\n"
   "- onCtrlClick: Button was clicked with the CTRL/CMD key down.\n"
   "- onAltClick: Button was clicked with the ALT key down.\n"
   "- onShiftClick: Button was clicked with the SHIFT key down.\n\n"
   
   "GuiControl::command or GuiControl::onAction() still work as before when per-modifier functionality is enabled.\n\n"
