Copy, Cut & Paste
Copy
"Copy" will really work like you expect it. It copies the selected region into the clipboard.
But it won't copy the region if it would lead to an incorrect string.
Cut
Cutting out means in this term not cutting out like in other text editors. Here you cut the part out and
throw the rest away. So you will get something like below if you choose "Cut" in the DNA window above.
If the cutted region would result in an incorrect DNA string it won't be cut, but there will appear a message
in the statusbar.
Paste
If you choose "Paste" from the Edit Menu or Ctrl-P you will get a little dialog where you can
choose from where you want to copy something and paste it.
Pasting will only paste a part of DNA at the end of the current DNA you are working with. It is
not possible to paste some DNA code in the middle or beginning.
Because pasting from clipboard will be the most useful option you cann choose this also per Ctrl-V.
Attention: Pasting checks if the two DNA parts you want to concatenate are matching together.
If they don't or if there are more than one possible solution to paste this two strings together
you will be informed.
