Those aren't all the commands now.
If you use the 3.0.5 builds there are more;

/xssselect - if you use this command after typing it and hitting return (or by selecting it from the plugins menu) after you type it you will get a cross on your screen and you can then click your left mouse buttom and pull it around any part of your screen. After this the part of the screen you've pulled a box around will be converted into an image and it will be sent to a contact.

To send an image of the active winow you can use /xssactive and then type a number of seconds after to take a picture.

For example if you wanted an image of this internet page you could type;
/xssactive 3
and then click open this browser window. After the 3 seconds countdown (displayed in the top of the screen) the window will be sent to your contact.

Another way to send your full window is to type /xssfull and it will take a full image of the screen, again you can use the countdown as you did before.

If you want to save the image yourself in a contact window click Plus > Plugins > Screenshot Sender 3 and select the option from the save menu, if you want to send it to a contact select the option from the send option.

Other options include checking for an update for the actual program itself, which is a straightforward option.
