Tour of PaintShop Pro

The next set of options are in the "Edit" menu. 

As you will see, most of them are greyed out atm - they become active when you have added something (colour, text, effects etc) to your image.  The most important greyed out ones are the "Undo" and "Redo" options.  These are lifesavers if you have done something to your image and you don't like it - you just hit "Undo".  If you decide you liked what you did after all, you can just hit "Redo" and it puts back what you've just taken off.

The "Cut" and "Copy" options are the same as in other Windows programmes.  You will notice a little arrow next to the "Paste" option - this houses lots of ways you can paste things into your image.  They are all greyed out atm, but when you have something on your "clipboard" they become active and you can do all sorts of things with them.  

The "Clear" option gets rid of everything that is on your image so make sure that this really is what you want to do (if you do it, and you find out that you want everything back, just hit "Redo"!)

The "Empty" option lets you get rid of everything on your clipboard (anything you've copied and pasted between images) and/or lets you get rid of all the history of the things you have done in PSP that session (if you choose to delete your "Command History" you won't be able to use the Redo/Undo feature for anything you had done previously in this session so make sure that you really do want to get rid of it - PSP does it automatically every time you close down PSP)
