Use Position Clues

A pen-based application should consider position clues in determining the user's intentions. The following offers a few examples of inferring the user's desires from the position of the ink:

• A gesture drawn over part of a selection should operate on the entire selection. In the same vein, a gesture or lasso that intersects more than a single letter of a word is probably meant for the entire word.

• Writing text on a line below existing text serves as a good indication the user intends the new text to go on a new line. In this case, an application can insert a newline character automatically.

• Text written over an insertion point should be inserted at the insertion point.
