We know how annoying it is when you start typing and all your words are in CAPs lock? After typing some text in a document you found that you typed too much text without noticing Caps Lock was on, you’re not alone sometimes this happens to everyone but make sure this doesn’t happen again for you, specially notebook users will have these type of problems as some keyboards and laptops have no activity indicators to know the user when any one of CAPs or NUM or Scroll Lock is turned on, CaPNotifier (Windows XP/Vista/7) is a freeware app that notifies you when either of Caps or Num lock is switched on/off. A discreet systray notification when you toggle caps, num, or scroll lock on or off.
How CaPNotifier works
Whenever NUM lock/CAPs/Scroll lock key is pressed on, notification pops up in the system tray alerting you that key is switched on/off, alarming is better option IMO as visual pop ups doesn’t help when you’re concentrating typing something seriously. Everytime you either switch on CAPs, NUM or Scroll lock a notification pops up from the the task bar, then fading away after a few seconds but enough for you to notice it.
CaPNotifier offers the options to alert when either of Shift or Control or Alt key is pressed on. You can click on “Show current State of Caps Lock and Num Lock “ button on program to know status of both keys.
CapSee, another great utility that does a similar job in Mac OS. The app can also alert you when you press shift, control, or alt, but those options are off by default.
