Screenshot of a settings window titled "General" with tabs for General, Displays, Icon, Sound, Updates, and About. Options include checkboxes for "Launch Captin at login" and "Show preferences on launch," both of which are unchecked. There are sliders for adjusting HUD window size between "Small" and "Large," and for setting "On duration" and "Off duration" with values of "0 s" and "1.5 s." Color options include a black background and text colors for "On" (yellow) and "Off" (red). A button labeled "Restore Default Setting" is at the bottom. The window is overlaid on a starry night sky background.
Captin Prefs


Unless you are an accomplished touch typist, which I am not, you probably spend a lot of time looking at the keyboard when working at your computer. Occasionally, those of us who type in this manner inadvertently hit the Caps Lock key unknowingly. When we finally check the display, we see a long string of text IN CAPITAL LETTERS. Fixing this is a PIA.

Enter Captin, a free little utility that lets you know in every way possible when you have turned on Caps Lock, and not just visually. You can set a sound warning too.
