Description
When your application starts and TMKeyboardStatusBar is created, all lights on the keyboard are under your program control. You can switch them on and off or lock in the state you want. This is especially useful if you have some dedicated controls for entering numbers, capital letters etc. It happens to me, all the time, to type in Delphi editor and then realize that all letters are in wrong case or instead of numbers (without NUM lock on) to loose the focus. If such a thing happens to you or your app. user, this status bar might help!

Properties
 | INumLock, ICapsLock, IScrollLock and IInsert are lights indicators There are several sub properties defined for each indicator: |
| Status is true if light is on. |
| Locked is used if you want to prevent user to change it from keyboard. |
| Color is obvious and |
| Text is the label you want to read in status bar. If you want two
different labels on status bar for some indicator, separate words with ;
(semicolon) You may want to use INS;OWR for insert status. If you don't use
semicolon, your default text will apear in upper case for ON status and in
lower case for OFF status of the indicator. |
| ILanguage - keyboard language layout for active control If you have to support input for different keyboard layouts, it might be convenient to inform the user which one is currently activated! |
| IFont - Font for active control |
All indicators are always active, even in the design time. You can set them to preferred status while entering some control and restore their state on exit.

There are two events I couldn't manage to find elsewhere!
| OnLightOn (VK_KEY: integer) ! It is fired whenever user or your application turn some of indicators ON. |
| OnLightOff (VK_KEY: integer) ! This might be useful if you are expecting numbers and NUM lock is turned OFF. At least a warning from your application would be appreciated from user! |
