Caffeine is a small tool that will prevent your PC from locking or going to sleep.It does this by simulating that you've released the F15 key once every 59 seconds by default. You can easily enable/disable Caffeine as well as setting time periods for activity or inactivity. Double-clicking the icon empties the coffee pot (that's what the icon is) and will temporarily disable the program.Since it operates by default at 59-second intervals you will be able to alter this behavior via command line switches:xx - where xx is a number which sets the number of seconds between simulated keypresses. This must be the first text on the command linestartoff - application starts disabled.exitafter: xx - application will terminate after xx minutesactivefor: xx - application will become inactive after xx minutesinactivefor: xx - application will become active after xx minutesappexit - terminates current running instance of applicationappon - makes the current running instance of the application activeappoff - makes the current running instance of the application inactiveapptoggle - toggles the running state of the current running instance of the applicationapptoggleshowdlg - toggles the running state, and shows dialogreplace - closes the current running instance, replacing itnoicon - does not show a task tray iconuseshift - simulate the shift key instead of F15showdlg - shows a dialog indicating whether caffeine is activeontaskbar - show a taskbar button (use with -showdlg)allowss - prevent sleep, but allow the screensaver to startkeypress - simulate a full key press, not just a key up event
