The icon is shown above - it's the leftmost one in the task tray, and this is all you see. Double-clicking the icon empties the coffee pot (that's what the icon is) and temporarily disables the program. Double-clicking it again refills the pot, and will keep your machine awake.
By default the app starts enabled, and works every 59 seconds. There are some command line switches you can use to alter this behaviour:

Compatibility
Caffeine works by simulating an F15 key up event every 59 seconds. Of all the key presses available, F15 is probably the least intrusive, and least likely to interfere with your work.
However, Caffeine might interfere with some apps:
- PowerPoint uses the F15 keypress to pause video in a slide
- Google Docs/Sheets
- Smartsheet
- Terminal emulation, e.g. Putty
Mac face primer gel. If you think any of these might cause you a problem, set the -useshift command line parameter.

Prevent your computer from going to sleep
If you have problems with your PC locking or going to sleep, caffeine will keep it awake. It works by simulating a keypress once every 59 seconds, so your machine thinks you're still working at the keyboard, so won't lock the screen or activate the screensaver.
The icon is shown above - it's the leftmost one in the task tray, and this is all you see. Double-clicking the icon empties the coffee pot (that's what the icon is) and temporarily disables the program. Double-clicking it again refills the pot, and will keep your machine awake.
By default the app starts enabled, and works every 59 seconds. There are some command line switches you can use to alter this behaviour:
xx- where xx is a number which sets the number of seconds between simulated keypresses.

Caffeine will be active only in hours with an x-onac- active only when the computer is on AC power (plugged in)
Comparison of methods
| Command line | Explanation |
| empty | The F15 'key up' event is used every 59 seconds. This is the traditional behavior so is well tested, but can cause issues with Putty sessions, PowerPoint, Google Docs or Smartsheet |
-useshift | Instead of F15, the shift key is used. This solves some of the issues with the above apps, but may cause the shift key to become 'unpressed' sometimes |
-key:xx | Instead of F15, the key specified by xx is used. Your choice of key could have side effects |
-keypress | This is more likely to cause side effects, as a full key down/key up is generated. It's included for compatibility with older systems which might need this |
-stes | Uses a different method (calling SetThreadExecutionState to tell Windows not to sleep. It works for me, with no side effects, but hasn't had enough testing for me to sure it's entirely better than using F15. Note that this will keep the machine awake, but not simulate activity, meaning any app which tracks user input will not see any. |
-allowss | The same as -stes but this time the screensaver can start. Note that this will keep the machine awake, but not simulate activity, meaning any app which tracks user input will not see any. |
