From the developer:
SketchEl is an interactive chemical molecule sketching tool and molecular spreadsheet data entry application. The feature set provided by the molecular sketcher is largely limited to the minimum features required to conveniently edit diagram representations of small molecule structures. Toolbars, templates, mouse gestures, keyboard shortcuts, utility commands and several view modes are offered in order to make this as convenient as possible.
