Btw I've opened an issue for this (for linux) last month https://pharo.fogbugz.com/f/cases/21732/left-click-ctrl-is-unsuable-on-Linux
> The Ctrl key does not have correct modifier flag when the mouse is pressed Note in the linked issue, that the modifier is present on mouseUp. My understanding is that mouseDown it is being replaced by a different event somewhere inside Pharo (maybe the mentioned InputEventSensor class>>swapMouseButtons ?)
