Hi Guys,
I am new to Keyboard Maestro, but have some experience with AutoHotkey on Windows. I really love the drag and drop interface which looks very userfriendly.
I have trouble to achieve is the following:
press shift + MMB will execute Alt + RMB
on release of MMB or shift => first (!!) release ALT, then release RMB
When I use the 'pause until conditions are met' action, it releases both the ALT and RMB at the same time. Inside the targeted app it makes a distinction which key is released first, so it gives an undesirable outcome. It needs to first release the alt (couple of miliseconds) and then release the RMB for the shortkey to work properly inside of the app. Thank you guys in advance for your time to help a newbie out
