Quick and dirty: "Sensor shiftPressed" The modification keys (shift/ctrl/alt/cmd?) is available at the MorphicEvent side see the class UserInputEvent (variable buttons + protocol modifier state). Adding a variable to TRAbstractMouseEvent (removing those at TRAbstractMouseClick) which hold this information + the same messages as in "modifier stae" + in each rtMouse... method in RTMorph add a line setting the button state from the evt argument to the RTEvent type (for example "ee modifierState: evt buttons") should make this information available for any mouse event in Roassal.

Mouse and keyboard events are usually captured by TRMorph and then converted into Roassal events, so check there.

Hello
I would like to ask whether is there any way to directly find out if specific key (shift in my case) is currently pressed. I am trying to implement own multi-selection of elements drawn on Roassal canvas, but I do not receive original MouseClick/Drag/whatever event with shiftKeyPressed, but I receive only Roassal selection event without this kind of information. It would require lots of modifications on Roassal part to forward such info (although it would be possible I suppose), so I am looking for a way to bypass it.
Any help is appreciated.
