Zoom (Focus) Editor for Visual Editors

Disclosed is a solution meant to assist editing complex documents by increasing the signal to noise ratio of visual editors.

The problem: one of the problems Visual Editors for all domains are confronted with is the limited screen real estate versus the theoretically unlimited document size.

The problem is more acute for editors that use relative dimensions for the content's widths and heights (calculated on parent/child and sibling relationships). In such an editor a single element would occupy the entire width of the screen, 2 horizontal elements will split the screen's width in 2 etc. Nested elements have their width limited by the width of their parent element and in turn will limit the size of their children elements. These editors do not fare well when the number of the elements and the number of nested elements increases. The problem is caused by the limit imposed by screen' size.

Visual editors that use explicit width/height for the content share the problem . While the screen's size is no longer the most important factor, when editing large documents the user can be easily distracted by elements that are of no interest at that time. The larger the document the more effort is required at every moment. An example is editing a nested table in another table in an HTML editor.

Text editors exhibit the problem at a lesser degree. Editing a specific chapter requires displaying the entire document and affects many functions: scrolling (scroll knobs become very small), printing (the user needs to provide the page limits for the chapter), affects various other views etc.

Several solutions have been employed to deal with this problem such as scrolling, zooming, collapsing parts of the document. Each of these solutions has its limitations:
- scrolling - the view of the edited document is changed but it does not influence the congestion
- zooming - indiscriminate zooming consume more screen for displaying the...
