| This idea has been developed and deployed to Canvas |
In the current DocViewer implementation, tools cannot be used to select an area that includes a portion of the document that is not yet onscreen. Attempts to get a document to "follow" the tool (via drag-scrolling) instead end the selection process at the point where the cursor exited the document area.
Please consider a modification where dragging the tool off the edge of the document window will instead scroll the window and select the revealed text/area of that document.
