Shift Key

Selectric	A Selectric Shift key will turn off the Caps Lock as soon as the Shift key is pressed.  This guaranties that every character typed with the Shift or Caps Lock on will in fact be a capitalized letter.
Programmer	A Programmer's Shift key acts almost like the Selectric type except that the Caps Lock key is only turned off if the character typed is alphabetic (the letters A - Z).  This still guaranties that each A - Z letter typed will be capitalized with either the Shift key or Caps Lock key, but allows names like WM_COMMAND to be typed with the Caps Lock not being turned off with the underscore.  Simply pressing and releasing the Shift key will also turn off the Caps Lock key.
PC	This uses the default behavior for the PC keyboard.  For most keyboards, that means that holding the Shift Key down while the Caps Lock is on will give a temporary lower case letter.
Scroll Lock

Keyboard Control	This setting allows the keyboard Scroll Lock key to set the Scroll Lock.
Always On	This setting locks the Scroll Lock ON regardless whether the keyboard Scroll Lock key is pressed.
Always Off	This setting locks the Scroll Lock OFF regardless whether the keyboard Scroll Lock key is pressed.

Num Lock

Keyboard Control	This setting allows the keyboard Num Lock key to set the Num Lock.
Always Numbers	This setting locks the Num Lock ON regardless of whether the keyboard Num Lock key is pressed.  This is useful for keyboards that have both separate cursor key pads and dual-use number and cursor pads.  Locking the Num Lock ON guaranties that the number pad will always produce numbers.
Always Off	This selection locks the Num Lock OFF so numeric keypad keys will produce either cursor movements on most desktop machines or characters on many laptops.
Icon

Normal	This selection will show the default sTOP tHAT! icon after sTOP tHAT! is first run.  The icon is only visible when other applications are not on top of it.
Hide when  not active	This selection will hide the sTOP tHAT! icon after another application gains keyboard control.  Hiding the icon is usually only done after the user has decided on fairly unchangeable settings.   To change sTOP tHAT! settings or to re-show the icon, simply re-run sTOP tHAT! from Program Manager and select the icon from the bottom of the screen to show the sTOP tHAT! menu.   This selection is only available on registered versions of sTOP tHAT!
Show Lock  Status	This selection turn sTOP tHAT! into an on screen indicator for the Scroll Lock, Caps Lock and Num Lock.  If any keyboard lock is on, the icon for sTOP tHAT! will indicate which lock is on.  The icon will also remain on to of other applications while any keyboard lock is on.
All preferences will be saved for the next time that sTOP tHAT! is run.
