Undo - ALT+BACKSPACE - reverses previous editing operation. You can do this repeatedly, within the limits of the program's Undo buffer. This "un-does" the last operation you performed, and then will reverse previous operations in the reverse order that they were performed, only If you've performed more than one change to the image. For example, if you adjust the color and don't like the result, immediately select this to "go back" to the previous version that existed prior to the color adjustment.

Redo - re-performs the previously un-done action. You can toggle the state of this and Undo back and forth to examine the last change you've made to a file as a way of judging if you like the effect.

Cut - SHIFT+DELETE - this "cuts" the selected region to the Windows clipboard. You must mark a region with the Select Area tool, it's the dotted box on the Painting tools palette. The area you cut will be "blanked out" with the background color you define in the Capture settings tabs or by using the Background color selector from the Painting tools palette. The default color for backgrounds and cutout regions is white.

Copy - CTRL+C - copies a marked region's data from the document to the clipboard, or if you've not marked a region, it copies the entire file's contents from the document into the clipboard.

Paste - CTRL+V - pastes data from the clipboard into the current document's workspace. You can move it by dragging it, but once you've stopped dragging and chosen another tool or moved to "view only" mode, the pasted material will become "glued" permanently on top of the previous image. (You can always Undo a paste using the Undo function.)

Paste as New Image - SHIFT+INSERT - if the clipboard contents are from a graphical source, they'll be pasted into HyperSnap-DX 5's application workspace as a new image (which you can then process and save using the program's features). If you've changed the currently-opened image but have not saved your changes, you will be prompted to do that first.

Copy Format - this function chooses which type of format to copy from the current image into the clipboard. Altering this advanced setting allows you to improve how well the data appears under certain circumstances. Generally only very advanced users will need to alter these settings in most cases. You may select what exact format type you want to be copied to the clipboard. These include device dependent bitmap, device independent bitmap or both. And you can change the color resolution of the image copied to clipboard. Finally, you can determine if you want this window minimized after copying is complete.
