     COMMANDS
     To use cliclick, you pass an arbitrary number of commands as arguments. A command consists of a command identifier (a string that tells cliclick what kind of action to perform) and usually one or more arguments to the command, which are separated from the command identifier with a colon. Example: “c:123,456” is the command for clicking (the “c” is the command identifier for clicking) at the position with x coordinate 123 and y coordinate 456. See below for a list of all commands and the arguments they expect.
     Whenever a command expects a pair of coordinates, you may provide relative values by prefixing the number with “+” or “-”. For example, “m:+50,+0” will move the mouse 50 pixels to the right. Of course, relative and absolute values can be mixed, and negative values are possible, so “c:100,-20” would be perfectly valid. (If you need to specify absolute negative values in case you have a setup with a second display arranged to the left of your main display, prefix the number with “=”, for instance “c:100,=-200”.)

 Limitations

 It is not possible to use cliclick before a user logs in, i.e.: to control the login window.
