You can use the Cut, Copy, and Paste items to move and copy regions of your icon, or the entire icon.
When you choose Cut on the Edit menu, the current region is removed from the icon and put on the clipboard. If you don't have a region currently defined, the entire icon is deleted and put on the clipboard.
To define a region, choose the Region drawing mode, move the pointer to the canvas where you want to start the region, press SELECT, drag the pointer to the opposite corner of the desired region, and release SELECT. The region is displayed by a dashed-line border. The lines of the border appear to be blinking, like the lighted sign of a theater marquee.
When you choose Copy on the Edit menu, the current region is copied to the clipboard but is not removed from the icon. If you don't have a region currently defined, the entire icon is copied to the clipboard.
Before choosing Paste on the Edit menu, define the region where you want to paste the contents of the clipboard. When you choose Paste on the Edit menu, the contents of the clipboard are copied to the icon, placed so that the upper left corner of the clipboard contents matches the upper left corner of the current region.
If you choose Paste from the keyboard (depending on your keyboard type), the contents of the clipboard are placed so that the upper left corner of the image goes to the position of the mouse.
