Undo provides the ability to revert back to the state the window was in just prior to your last action. The last action can be a cut, a paste, or a mouse click followed by typing. The action to be “undone” will be stated in place of the simple Undo (e.g. undo paste, undo style change, etc.).
Cut, Copy, and Paste function as they do in other Macintosh applications.
When pasting segments of DNA into sites on other constructs or elsewhere in the same construct, the ends of the segment are examined to see if they are compatible with the site into which the fragment is being pasted. If they are not, you will see a ligation dialog box and be asked to adjust the ends so that the ligation can be done.
A special case of copying and pasting deals with the copying of marked sites from the Construct Window followed by pasting into either a Gel or Illustration Window. When pasting into a Gel Window, the Gene Construction Kit assumes that you are doing a restriction enzyme digest and will create a lane on the gel showing the fragments that would result from digesting the DNA with those enzymes. When pasting into an Illustration Window, the Gene Construction Kit creates a legend.
Clear will delete whatever is selected. It will not replace anything that is on the clipboard.
Special Paste serves to provide special treatment of fragments before they are pasted. Inverting the fragment before pasting gives you the option of inverting a fragment before pasting. Options are also available to Trim Ends or Fill Ends of all fragments before pasting. The Leave Ends Alone option will not treat the ends in any special way.
Select All will select all of the items of the type you have currently selected (e.g. - if you have selected a marked site, Select All will select all the marked sites). In the Gel Window, Select All will select all the gel lanes. In the Illustration Window, Select All will select all the objects in the Illustration.
Show/Hide Clipboard will either show or hide a window showing the contents of the clipboard.
Show Overview is active only from the Illustration Window and will shrink the entire illustration to fit on the screen. The cursor changes to a small magnifying glass. Clicking the magnifying glass at a specific location in the overview window will cause the image to return to normal size and will center the image around the site that was clicked.
Show Selection is active in every window except the List Window. It will make visible any object that is selected. If the selection is out of view, it will be brought into view.
Show/Hide Page Breaks is functional in all windows. It will show a line on the screen indicating the border of the current page. It is particularly useful in the Construct and Illustration windows. Page breaks are automatically shown in the sequence view of a construct.
Set Gel/Construct Margins… allows you to set the top, left, bottom, and right margins for the Gel and Construct windows. These margins will be used on screen to provide room for larger font sizes for gel legends or construct markers (in either the sequence view or the graphics view. Margins set for constructs will also be in effect (as the construct border) when the construct is pasted into an Illustration Window.
