There is already some documentation of the editing tool available. see http://doc.robofont.com/documentation/tools/editing-tool/ straight line to curve: alt+drag the straight line alt+drag one of the oncurve points deleting bcps: delete a bcp will remove both bcps alt delete a bcp will algign the bcp on top of the oncurve point RoboFont tries to bundle similar actions to one and the same shortcut. Bcp handle modifications are mostly all bundle with the "command" key. modifying curves by grabbing the curve: only dragging: moving all points command + drag: adjusting the bcp handles shift + drag: drag the points on 0° 45° or 90° alt + drag: un-smooth the oncurve points and move the bcps only shift + alt + drag: lock the bcp on 0° 45° 90°
