Described herein are systems, methods, and apparatus for electronically drawing and editing representations of chemical structures using an intuitive user interface. This user interface, the context-aware virtual keyboard, makes it faster and easier to draw and edit chemical structure representations by guiding the user through the sequence of steps required to produce the representation in a context-based, non-linear fashion. The context-based virtual keyboard allows a user to quickly create graphical representations of complex chemical structures by using the structure itself as a basis for presenting efficient options for subsequent drawing/editing steps. Different possible and/or likely actions (e.g., edits to a chemical structure being drawn) are presented to the user based on a selected navigation position on the drawing. Thus, a user can efficiently and intuitively modify a chemical structure drawing without the tedious manual selection of portions of the chemical structure and without searching through complicated menus.
